There was an agency in my area with whom I was a regular.  I got to know all the girls, and became friends with the lady who ran the show.  Two or three times a year, the agency owner would book a suite and eight to ten adjacent rooms in a high-end hotel.  She would then send invitations to her preferred clients.  The clients would pay a small fee, like $75, to attend.  This was used for the open bar and the excellent catered food in the suite.  Each of the girls would have a sign-up sheet on which guests would place their names.  Each girl was assigned one of the rooms, and would ask clients to join her in the order of the names on their list.  The clients would pay the girls $50 per 15 minutes, with a 30 minute maximum.  While not otherwise engaged, everyone socialized in the suite.  There were even games.  The discussions were funny and interesting.  There was a lot of laughing and kidding around on everyone's part -- client and provider.  It was was a great time.  At the end of the night, the girls would all kick in 10% of their fees, choose a charity, and donate the money.

Then, there was another agency...
The hotel was a fleabag.  The open bar was several six-packs of warm, domestic beer, the food was stale corn chips and the girls behaved as if they'd rather be anywhere else.

If you know the agency (or in your case, the group of providers), and you have some kind of relationship, you should have a good time.  Otherwise, you'd probably have more fun booking a double on your own turf.
