Some providers offer 30 minute as well as hour sessions.  From the providers point of view how do you feel about one vs the other?

Her rate. How does her 30 minute rate compare to her 1 hour rate? Often a girl will have a rate nearly as high for 30 minutes as for a full hour, instead of half as much. So she's trying to push you to the later time slot because she doesn't really want to book for a half hour.

Tells me they're a high volume provider which in my experience leads to a rushed session.

You could tell a lot by rates.  Some providers also have 15 min appointments or "blow and go" and no I am not referring to just low quality ladies.  I have seen ladies who (unknowingly probably) have overall TER ratings of between 8.5 and 9 advertise these.  I did not partake, but found it interesting nevertheless.  Providers will also advertise 30 min/1 hr appointments with little differences (rates) between those  and longer appointments to see if you are cheap.  Example: $400/hr or $500/90 min.  Select a 1 hr appointment with this chick and you are labeled as a cheapo before you open the door.    

want to speak up for the providers when someone asks them a question.

Of providers that refuse to book under 4hrs.

The going rate at my fav agency now is $280 for an hour, but $200 for 30 min and $240 for 40 min.  I often ask the girls about 30 minutes and they tell me they understand that married guys coming from work on their way home or getting a little on their lunch hour can't do an hour without making their wife suspicious or getting in trouble at work, and these guys are mostly good guys and are not too demanding given the time constraints.  However, they hate the guys that are doing 30 minutes because they're cheap, and they complain if they don't get everything on the one-hour menu during the 30 minute session they booked, so its a lot more work and they are often exhausted after a 30 minute session. Its no secret they would rather have an hour, so the rate scale is a bit punitive in that regard to some guys that are sneaking around and can't do more than 30 minutes at a time.  A few years back there was one guy the girls called, "the lunch guy."  He came everyday to see one of them from 12:00 t0 12:30, like clockwork five days a week, so he wasn't doing half hours because he was cheap.  

and then some of the actually cheap mongers would try to find out what it really cost me on a "per pop" basis and I told them that a three night trip to Costa Rica typically would cost me about five grand "if" I didn't lose anything gambling.

Well, once you ignore the overhead you are cheap. lol

Yeah, when you're vacationing specifically for pussy, I think you have to count the rest of the overhead into your hobby budget.  Its not just the direct compensation, its the whole package.  I had to explain this to a guy at my gym a few months ago before they closed for Covid.  He was flashing around his photos of his sex-trip to the Philippines, and emphasizing the low prices for pussy there, and he was only doing one girl a night, so he did not qualify as a whore-mongering pig in my book. I told him to add in what he spent to get there, his hotel expenses, meals and nightly bar tab, and then divide over again by the number of girls he saw.  He agreed to your point.  He could have stayed home and spent less.  LOL

That could explain 30 minute vs hour rates.  (180 vs 220 around here)
.
But there has to be a different explanation for the equally weird 90 vs 120 Kgirl rates.  
.
The rate for 90 minutes is the sum of the hour rate and 30 minute rate, and the 2 hour rate is just twice the hour rate.  In other words, the same penalty is applied to 90 minutes as is applied to 30 minutes.  That's directly contrary to the girls-work-harder explanation of the 30 minute rate.  
.
This can appear as if it's the booker's convenience that is the dominant consideration, rather than the providers'.

Touring just for sex sounds a little boring to me. But I haven’t ever really tried to plan one. I guess if I threw in other activities to mix it up it could be great.  
Even when this old body was up to 7 or more girls a day (on weekends) when I was traveling in Brazil for work, I was quite ready to get back to work when the weekend was over and slowing down to one or two a day or whenever I could find the time during the week.
That said, combining a lot of sex with sight-seeing, bike touring, running, hiking, and other activities sounds like a lot of fun.
So far, though, all of my sex touring has been paid for by work. So, travel, food and hotel have all been free to me. And I have no complaints.
At a termas in Rio a 30 minute session makes sense to me. You pull the girl off the floor, have some fun and go back out to meet some more until it’s time to try another place because you’ve spent time with the hottest girls there already.

That is very rare.  Most of the providers that claim - well it is more aspirational than reality.  

I’ve done more than a few of the 90 minute sessions.  

I used to do a lot of 90's until I moved my office closer to Kgirl-central in OC.  Then I switched to 2 hours.  90's are kind of a rip off money-wise, but if its all you have time for, it is what it is, right?  The agency I give the most business to charges $280 for one hour, $560 for two hours, and $480 for 90 minutes. They arrive at the price by adding the one hour ($280) and 30 min ($200) prices together.  For eighty bucks more you can get a full two hours.  Totally worth it unless you just can't make the time work.  I need two hours to get two pops in during the last few years, so I don't do 90's anymore at all.  

There was a seasoned and trusted monger on Neurotic Donkey who always did a half hour first time for recon purposes; to see who he wanted to repeat with.  The girls got wind of him and he wound up getting special treatment from those kgirls who were looking for quality regulars.

That's one reason why I always schedule overseas travel for longer than three days - in fact usually at least 10 days.  When  you calculate the aggregate rates for pussy in a so-called cheap location, it's still going to be two to four times the straight session rate. Airfare, hotel, food & drinks (for me and the women), local transportation, sight seeing & and tourist crap for my cover story all ads up.  
.
My last trip was to DR where I spent quality time with 6 women, all 7-9+ and 19 to 26 years old (yes I have pics - no I will not share them). The sessions were less than $100 for about 2 to 3 hours. But I spent 60% of my budget on business class airfare. So the aggregate was much, much higher.... and totally worth it.

Makes sense from a monger perspective.  
But what about the girls' and orgs' perspective?
Do you have a theory for why the orgs apply a stiff penalty to 90 minutes vs 120 or 60?  
Others have just called it "hooker math" but the POs/bookers aren't dumb hookers.

400.00 is not being cheap I don’t know about most guys on here but I really don’t like paying more for a hr then I make in a day(around 500.00) I think these providers are getting ridiculous with there donations it a few I have seen in the past that I would love to see again but it’s hard for me to pay more then 500.00 for the hr which they both now charge 600.00

If You got The Money Honey..
I've got the Time..

Given my employer is just squeaking by, no travel for most if not all of the year.

I tried the 30 minute thing for checking out new providers. It just did not work for me. 60 minutes is better and 90 is almost perfect. Lots of girls can keep things going for a good 60 minute session. If that’s all you’re after a 30 minute might be fine.
But a typical one hour session just leaves me horny for more. And I’m out not just the money. I’m out the travel, prep and warm-up time for the girl.  
If a 90 minute session fails because she starts repeating or running out of steam early, I just gracefully walk and go to my plan B.

with judging a new provider on the basis of a 30 minute session is that you will most likely not get the full menu with enough time to evaluate her skills, and therefore, not really be able to gauge her strengths and weaknesses accurately.  When it comes to older guys, the girls tell me that many are disappointed  in 30 minutes sessions because if you get to the 25-minute mark and you haven't been able to cum yet, you are going to get finished off with a vigorous handjob, probably something you could have stayed home and done yourself.  

i do not offer half hours for a few reasons. First of all, I do not see alot of guys in a day. Usually 1, 2 max. Touring may vary. I put alot of effort into getting ready and being my best. I personally don't feel it is worth all the effort for a 30 minute appointment. The main reason is that you can't have much of a connection with someone in 30 minutes. It just isn't my style. I don't like being rushed..

I don't advertise 30 mins since rarely ever do with new clients. I'm a gfe provider since its dovetails with my caretaker personality. Breaking the ice with new clients (usually with a drink) & getting a feel for what they desire is critical (imho) for a 1st sesh.
Occasionally do do them with ongoing as an accommodation to them (can be $ or can be time thingy). Usual scenarios of what can ensue:
-we know each other, are considerate of type of sesh, and s'all good
-i'm not clock watcher type, so next thing ya know its 45 mins
-client isn't considerate of time, pushes envelope, i push back on a subsequent sesh & feel crappy, and then cut him off from future 30 mins sessions.
Bottom line, I liken it to the Woody Hayes quote "Only three things can happen when you pass (a completion, an incompletion, and an interception) and two of them are bad."
Sorry, not sorry.

I normally do not do the 15/30 QV but sometimes that is just what I am in the mood for. I appreciate that the option is there especially if the lady is hot.

I'm not as prolific as some here as of late, but 30 minutes is a waste of time. I won't do less than 2 hours, that's just me. I'm not saying I fuck for 2 hours straight, I wish, but I actually dig hanging out with my lady friends before, during, and after.

Ahhh, the memories of rushing back to the dorm between classes or finding an empty room at a house party for a quick fuck with a girlfriend. That's what a great 30-minute session is all about.  

I can’t say I absolutely never do quickie sessions.  
I used to know a lovely provider at a local AMP. She had told me if I ever wanted to see her before she started working to just show up at the door and she’d let me in.
So, on mornings when I was, to quote from Beetlejuice, “feeling a little anxious” I’d drop by and she’d let me in and then push me up against the wall and suck me dry. And I’d be on my way in a far better mood than when I got there. Those morning blowjobs (I really miss them) never took more than 30 minutes.

Personally it doesnt matter to me either way. I can do a HH session just as effectively as i would an hour or two. I think the question is....can YOU reach your  point of satisfaction within that allotted time frame?

Offered hhr years ago. I just outgrew it and also didn't see the point of doing a date that was shorter than the amount of time/effort it took me to get ready for it so....yeah.  

I don't think any of the guys mentioned the following reasons for opting for a 30-minute session, so here they are.

I will add one more.  In the age of COVID, how does one explain being away from home for an hour or more?  Not as much of a problem now that things have opened up a bit, but still a hard sell if one has kids and cannot business  travel.
