I haven't been to Sandals or one of those for singles but I went to an all inclusive place in Jamaica once mostly for couples and it was great. Great coffee, pina coladas and weed. Beautiful place. What else does one need? To get laid? I'm sure that's also available. Go for it. Bring condoms.
I do not really know cuz I have never been to one- but supposedly- rich,coupled or newly divorced middle-age go there...They are trying to satisfy their repressed sexuality that they have in their everyday "humdrum" lives-when they go there- because back where they are- they can't they may be afraind what others think/say about it...I guess many are surburbanites that may get horny and desire to do something wild...I saw one on t.v. a couple of months back and -from what I observed it was portrayed to be like that...But then again there are different ones out there- and u also can not believe everything on t.v....so -u might have to check it out 4 u...
It's just a resort, nice beaches, lots of outdoor stuff to do... most folks are completely naked, it's quite freeing. Just an awesome beach resort envirnonment, with a very liberal attitude towards each other and nudity... you make friends very quickly!
I have some married friends that go to Hedonism II every year. They like the whole having sex anywhere thing going on there. And there's alot of swapping going on, too. I don't THINK my friends go for that, but I think they like watching other people have sex and the flirting and such. Plus, dinner time is "sluts on parade". You have to be 'dressed' for dinner, but the women just whore it up with their oufits. There is a nude side and a clothed (textile) side to Hedonsim II. There is a book called the Naked Truth to Hedonism II if you need more info.
