Fairly new to this hobby, I'm completely fascinated by it. Do any providers/hobbyists have any tips on what they or their providers have done to make the overall experience better? Example: having mints out for the hobbyists. Just trying to improve every way I can!

I recall a date early in my hobby life...   the gal had a chair set out to recieve my clothes.  It was a really nice touch.  Another had a small basket on the dresser, beside the chair for keys, phones &  change so they'd not be misplaced.  
A warm face cloth to clean a guy up after.  Wipes are so cold & tacky.

1) have his fav drink, be it alcoholic or not, waiting

I like the idea of a  basket as mentioned above.  I've usually put my clothes on a chair or on a small table but rarely on the floor.

coffee, tea or soft drink which is fine for a hour or less.  A multi hour, light alcohol would be ok but ask first...  some guys & gals might not take it.  
I like to bring a fruity jar candle but have arrived to find other candles lit...   I like having soft soap & a clean towel for handwashing.  (He wants to put his fingers where?)  & have brought them myself & left them.  
Be ready with approach instructions...   He should be given instructions to a designated "call point"...  maybe a near by intersection or hotel entrace...   have detailed instructions from there.  Say he has to come in the hotel entrance...  walk by the front desk (will be on your right), straight ahead, elevator to your left.  That keeps him from fumbling the approach & looking dumb.

Sorry boys. You giving advice to a newbie provider on this question it's like a guy telling women what to expect on the third trimester of their pregnancy. Just my 0.02C

The guys are the clients, Sash. What well run biz doesn't check in with what their clients needs/wants? She also specifically asked the guys our thoughts.

and it's always good to get a variety of opinions. I don't think I would disagree with anything written. I'll only add music (choose something inoffensive or inquire about musical tastes beforehand), and to know your limits in terms of boundaries. Don't be tempted to do something you're not OK with just to make money- you won't like yourself for doing it and the person you're with will sense that you're uncomfortable (unless they're arseholes who don't give a sh*t and are persuading you to do something you don't want to). And very important- follow your intuition. It's your best friend- both for keeping you safe and for making your friends happy. Oh- and be as warm and welcoming as you can when you meet someone for the first time-put them at ease. Being comfortable with yourself will help you with that, so if you are already a confident lady, you'll do fine.  

When a guy gives a provider a tip. It's more about what they like personally or think it's appropriate. Like someone mentioning about the hot cloths instead of a wet wipe because it's cold and "tacky". What's wrong with that advice? Well... He's not the one calling the front desk asking for cloths over and over. One needs to be discrete. That is merely one instance where hearing advice from a guy doesn't really help. She doesn't need to raise red flags, and one wet wipe is just as good, and just because someone thinks it's tacky, doesn't mean that's not the best way to do it.  

away) used to keep a small crock pot type appliance on the end table which was filled with warm washcloths. A very nice touch.

if either the provider or the guy is loud when having an orgasm(s).

be yourself. Be authentic, genuine and do what comes naturally for you, and I'm quite sure you will be a huge success here. All the lil details do matter, but that's the most important one IMO.  

...to her in call location when it was a hotel room. It's about the level of service the lady wants to provide. She is free to take our advice or not. She's free to modify it if she chooses. But she does need to hear what we have to say. Especially when she asked us for our thoughts.

Yes, I have only had one provider give directions from when you walk into the hotel.

I saw her stack of clean sheets, and they did not match the hotel sheets, she says she asked for room wit double beds because she has that size ... Feels better then my vision of how many clients have been on that duvet. I don't care if it's pulled tight. This same provider has also brought a bunch of beach towels.

Let me add a +1 to the music.  It's easy today to have a music play lists...  of different styles...  and a bonus as you learn them you'll have a hint how the time is progressing.  Early in my hobby life, a gal did indeed have a "boom box" aimed toward the door where it was quite a bit louder but only a nice background level at the bed.    

I have visited one provider that brings everything with her to her in call. Fresh bed linens, towels and wash cloths and an assortment of sample size soaps and body wash. Granted that she does not fly cross country but I felt like the extra mile had been traveled.

I see this topic isn't too old. If any are still reading, here's some thoughts. Not to beat a dead horse, but having the provider use a warm wet cloth to clean up is a really nice touch that can influence your view of the entire session.  

I bring this up because I have had some awkward experiences with this recently.  I have seen providers who are well reviewed and had nice websites but when I saw them, they simply did not smell good.  Either they need some deodorant or they did not wash their anus properly.   I think some ladies might get a bit casual about the hygiene thing and do not bring their "A" game.  Meanwhile, I am very particular about making sure I am clean and smelling good everywhere.  Please do not slack off.

now im questioning whether or not to ditch the we wipes ... lol
