NRW Area (Cologne/Bonn/Duesseldorf Area):
NRW stands for Nordrheinwestfalen...or, in English, the Rhine/Ruhr Valley.
Best clubs:
1) Golden Time (Brueggen)...long considered the go-to club in the area
1a) Living Room (Kaarst) (same owner as GT, excellent to go there in evening after GT)
3) Villa Vertigo (Grefrath)(lineups hit and miss, but facility outstanding)
4) Babylon (Elsdorf) former #1 choice in area, good facility, back on the upswing
5) Finca Erotica (Dierdorf) about halfway back to Frankfurt, smaller club with excellent talent. Never have left disappointed.
6) Bernd's (Lichtenberg)...the original modern FKK/brothel club. These days, mostly Milfy, but outstanding talent. Smaller club, 15 ladies, international lineup. Closed weekends, and open only til 1a during the week. Definitely must visit, particularly if you like the 35+yo talent.
Frankfurt Area:
1) Oase (Burgholzhausen) Ancient facility, they always need to keep putting money into it, and smoky like a 3-alarm fire in the evening in the main room, but many of the same talent has worked there for years now, so somebody must be doing something right. Very large club, and probabyl the best day shift of all the clubs.
2) World (Giessen) Maybe the best facility of the entire list, good food (all that fucking and sucking, one gets hungry!), excellent selection on weekends, lots of parties on Saturday, many promos. Good deals for local regulars, too.
3) Palace (Frankfurt) Only major club that's in central Frankfurt, they charge more to get in (because you can take public trans to get there; it's 200m from the U-Bahn station). Good, modern facility, but not for rookies...lots of sharks among the girls, lots of upselling. Still a good lineup, but you have to be patient when interviewing the girl, and don't forget to clock your sessions. Yes...I'm serious. Go, say, 2 minutes over, a lot of girls will try to work you for an extra E50).
Anyway, if I missed one...or your favorite isn't on that list, let's discuss. Many smaller FKKs in Germany, but these ones are the surest bets.
I have yet to make it over to the Rhine area. I have spent most of my time in Bavaria (love the beer, food , and scenery).
The Colosseum: Located in Augsberg a short train ride outside of Munich; Not the personal attention that I like. Food and drink very limited. The girls herd men through the rooms like cattle. But there is some decent looking talent, but on a busy night they are nailing one guy after another.
The Globe: A short train ride outside of Zurich, Switzerland; I loved this place. Lots of beautiful talent. Pretty good personal attention. The night I was there a lot of bbbj and DFK going on around every corner. I ended up with a gorgeous 9+ Polish girl. Great Time.
Babylon: Vienna, Austria; I got stood up by a girl who was to meet me there for 2 days. I elected to make the most of my time in Vienna and hit up Babylon last minute. Very nice place. More expensive than the average FKK, but also more elegant. The girls are dressed in evening attire (not the usual naked, bikini, or lingerie at most places). Food and alcoholic drinks included with door charge. The ladies will sit and have dinner with you and/or drinks. There is no pressure or hassling. You have to approach them. The rooms are nice. Each with an open shower and hot tub. Talent ranged in the 7-9 range with a good mixture. I got lucky and struck a convo with the hottest one there. A gorgeous straight out of Playboy quality Euroasian woman. A body and face of an angel. She wasn't the best kisser, but she was great in all other fields. I had spent a great two hours with her in the room and shower. Had a blast.
For us monolinguals, how much English is spoken at these clubs...a little? a lot? varies by location?
You'll get by. Many of the girls are from Eastern Europe, Italy or Spain so English is quite common, but it may limit your options as others may have none.
The lack of German hampers me somewhat in that it's impossible to build up any sort of rapport with the girls, staff, and other guys in the club. Lack of German really hurts for the few times I've gone as a single guy to a swinger's club.
On the flip side, you will find guys, girls, and staff who will want to try their English on you, which can be fun also.
I did forget Artmeus (Berlin)...never been there, but hear mixed reports. It's a megaclub the size of the three FRA clubs mentioned.
Re Globe: was told Swiss law requires CBJ, but, you never know...large number of legal brothels in CH. I believe you can be as young as 17 and be able to work in a brothel there (not my deal, just sayin').
Know Babylon well....very upscale brothel managed by former Marriott executives. You're looking at a $400 experience minimum, several high rollers, athletes, F1 drivers, etc...been known to drop over $10K in an evening there (lots and lots of champagne!). Door charge is usually waived if you're a regular. Also, if you're looking scruffy, don't expect to be let in.
Generally, with the exception of a couple FKK-style clubs in CH and CZ, FKK is pretty much exclusively a German deal.
I also found another one with this link. Goldentime looks the best, but Babylon in Austria looked cool as well as the Globe in Zurich.
You guys ever see this one? Thanks for the resource by the way.

For the poster that didn't like Colosseum (too businesslike) then he probably won't like Artemus either. It's much bigger, with a bigger range of options. Personally, I thought it was great but I was lucky - a slow Sunday evening meant a better ratio of providers to customers and generally provided a more relaxed atmosphere.
The list is pretty much right on, PHG could also be added.
Trivia Question:
What club did the owner of GT and LR own before GT and LR even existed?
Finca tends to be better in the afternoon evenings from my experience. The girls change often and I've yet to see the same faces on previous trips. That tells you something. They offer a happy hour rate and its a nice place on warm days out at the pool.
More Triva:
Did you know they've connected with World?
The people that brought you Finca Erotica managed what club prior to Finca?
I would not use the word "modern" when describing Bernd's. Did you know they used to have two clubs and the previous one which was closed years ago was actually better? The famous Katja got her start there. If you want a definition for FKK club then Bernd's would be it. Most Germans and girls that work there refer to it as "Schieferhof"the name of the street its located on.
Hours, I believe its only open till 1am on Fridays and closes the rest of the week at 12. They won't let you in after 11:30pm in any event.
The reason that Bernd's has those hours is not by choice but the fact that it's located in a family zone and small town. Same management had re-done Sudbad in Koln and many of the women from the big B will moon light at the new club. Now called Salon Rouge. Should you want to visit a club with late hours or weekends give them a try. Don't take a cab as they cab driver gets a kick back and this might affect your entry rate. I would not limit them to just Milfs, I've seen my share of 18-25 year olds. Perhaps its those 10 year plus gals that have been there so long that stand out.
Oase: Not sure if I'd call it ancient. Oase has been in a race since the days of Atlantis in Altenstadt. Since Atlantis decided to up the entry from 50 Euros, Oase had no choice but to compete with secure parking, larger pool, large jacuzzi and hot food. All which they claimed was the reason for the rate increase which increased from 50-60 and then 65. Palace by the way did not stop and went as high as 75.
Did you know that there was a time not too long ago when the women of Palace wanted to enforce the 15 minute rule. Yes 50 Euros per 15 minutes. In my book Palace, World and Oase are all shark clubs with women that prey on the newbie. Palace is great for the first time guy who does not have much time and located near Frankfurt. Its the closet FKk to the airport.
They charge more because people pay it. It's the official tourist trap as far as most FKK guys. They're close to the Messe (convention center) which means lots of men who don't care about cost. Women know this too so some will take advantage of you. This can also happen at Oase and World. Not too long ago Oase management worked out a deal with the taxi companies to pay them the same or more then the Palace was willing to fork out as commissions. This means many more Messe visitors were taken to Oase by taxi drivers.
Oase has grown and been re-modeled many times. If you had visited 10 years ago you would recall the red carpet and bamboo interior of the lounge just next to the bar. There was not dance pole room or Kino those are new. The rooms at the far left rear are all fairly new as well. Maybe due to the old Roman look one thinks of this place as ancient. Most of it is fairly new, rooms, mirrors, etc. They don't need to put money into it, the owner is always competing to be the biggest and No. 1. You can sense that as well by reading their ads and website. Oase might not have the land that World does but no one comes to close to having as many women at one time.
Triva:
What famous place did the owner of Oase model his club after?
World may seem big but when it comes down to it you're walking a gaunlet from around the bar down the stairs to the Saunas and back. Which is basically what Oase and Palace offer. During the day, sure you can walk the garden and grounds. But what good is BIG and what is BIG if you don't have the staff of women to fill that area. Lets not forget its over twice the time and distance of Oase. Not sure what we would use as a measure of BEST facility. It's got plenty of room to expand but what does it have that the others don't? Nothing, it's personal taste in my humble opinion. Bar was recently re-worked and hated by many. Now one bar tender has to look over her shoulder and a huge number of guests. Before you could look across the room from any spot in the main room. Now this huge bar in the middle blocks your view and creates one huge mess during peak times. Lets not forget the huge numbers of Bulgarin, Romanian and eastern block gals that seem to have forced out other women. By the way the deals are not for locals or regulars alone, weekdays they offer a 3 for 2 rate. If three guys enter together then only 2 pay. Some parties they even increase the 65 entry rate I've heard so ask if you don't know.
Number 6 is pretty much right on and appears to know his stuff, I did not mean to start anything and just wanted to add my two cents. Again it's not written in stone and I could be wrong, just my humble opinion. Please correct me if wrong.
Yes RULE 1, wear a watch, make it known you check the time, better yet wear a watch with a stop watch and set the time. She'll be watching her watch you can bet on that. While not all women do this, many do and going over by 2 minutes can cost you 50 more Euros around Frankfurt. I've seen and witnessed many a fight at the front desk when it comes to slight over time. Sometimes the gal wins and sometimes the customer does.
Its not a bad ideal to visit the first time with a friend or look up fkk tour on google and join a tour. They're staff knows the clubs, girls and owners better then we'll ever know and can make your first trip trouble free and easy.
The greatest FKK of all time, the dearly departed Atlantis.
They've also ran brothels in AT, CZ and BR with over 30 years experience (also vaguely remember Egon mentioning Macau once too, but I could be in error..maybe Mexico?).
Anything Egon or Heinz is running, I'm there. Do I go to the head of the class now? 
The stopwatch thing is more important at Palace than Oase or World; it's a question of what the management will let the girls get away with. As a former Paradies (Palace when is was a smaller club) regular, I actually boycotted them for a couple of years because they treat the guys like marks. I don't see that bullshit happening at World or Oase, I really don't. Palace caters to the pimps and could care less about the punters...and why should they? Whenever the Messe is booked for something, they're jammed solid every night. But, there are some wonderful ladies who work Palace too, so...and yes the E75 thing ticks me off to no end, it's not about the extra 10 Euros, it's the principle.
Finca and World are supposed to be affiliated. Finca is a sleeper, particularly on the weekends. They're on my "only clubs that matter" list.
