@bbzh Thanks. You're not overanalysing, I have been thinking about those scenarios too. Usually I want to be in control too so to let go and see what happens is a change for me as well. I have decided to go because it has always been a fantasy and this may be the only opportunity I get to experience it. It could very well be a big disappointment for the reasons you mention (and I will make sure I have checked all info I need if I want to leave early). But at least I will have tried it. And it's only 72 hours, I'll manage to get through them even if it doesn't play out as I think it will and some of the scenarios occur that you describe. Some of the tops I will already have met at their regular parties, some will be new. So I know at least some like my hole And I know the hosts do! Same for knowing or not knowing the other bottoms btw. But I'm a voyeur as well, so even if other bottoms get more action than me or if tops start fucking the vers tops it'll be fun. I'll volunteer to be the cameraman (if that's what some want)!
About the cost splitting. It's supposed to be fun for all and the organisers are trying to set this up to be fun for all. They want guys to return for a next time or to their regular BB parties. And they will organise it, book the house, provide the supplies etc. Travel costs are your own. And yes, they decide who sleeps where and so on, but they know all the guys and even though I don't know yet what arrangement they make I'm sure they will take personalities and 'types' into account (or I hope so...).
They are still looking at houses and haven't decided yet but (when I asked) they sent me a few pics of houses they booked the previous times to give me an idea. It may be one of these one again (if available) or another one.
Anyway, it may not be the best experience of my life as you say but I do hope it will turn out to be fun. And if not, then follow an exit strategy.
