I know what your talking about. I've been there/done that, myself. That kind of party is good but what I was thinking of in this thread was a little different in that I didn't want any money changing hands except as the expense charge between the guys to the banker and then the division among the ladies later.
I also wanted the fees high enough that top quality ladies would be attracted to it. That's very important to me and as I remember, to others who I've played with in the past.
It's a given that many hobbyists, though they'd like to come, wouldn't be able to afford this. But, if 6-7 could and, as A1 says, the other expenses could be kept down, then it could be a party for the ages.
BTW A1, I have reservations about a 36 hour gig. That's a long time for the ladies to be away from their operation and I know many of the guys would find it hard to get away from home for that long. Others may have a different opinion but I would think 12 hours would be about max for the main party. Some might want to layover and that would be fine if it could be arranged.
So far as the ladies selected, they would have to be ladies who loved sex. B/G, G/G, B/G/B, G/B/G, it's all good but no pain or scat, no cameras or cells w/camera and no lady or gent forced into something they aren't right with.
