I appreciate your concern.
Truth be told, if you've got a midnight appointment with an sp, she possibly has already been with a few guys that day before you.
Again, number of couples and hours and choice of participants are important.
I say maximize the hours (if you can't hack an overnighter+ you are not suitable) minimize the number of couples to a select (with the desire to be there) and hopefully desirable group.
If it is your sole purpose to have quality time with each and every sp at the gig, you may be disappointed. You may not get msog, exclusivity, intense sexual connection with them all. You may posess that already with the gal you bring and you will get a chance to sample it with the others.
I am expecting a party atmosphere. Knowing that the girls are being compensated for their time meens you'll get some good girly action to watch while you sip some wine or a brew and a round with any others that catch your eye.
As far as sloppy seconds etc. I do take some offense to that. I am planning to acquire a suite with 2 bathrooms, many towels, mouthwash and all other neccesities. If a lady can't wash between her legs and enjoy a break before she's off with the next one, she is not suitable either.
