I believe that Hedonism is what you are looking for. There is only one Hedonism, Hedo 2. (Hedo 3 closed several years ago.) The staff does a great job of keeping it clean. You should understand that the place is over 30 years old, but the new owners have spent millions on upgrading the rooms, fixing infrastructure, better food, etc. Part of this has been replacing air conditioners which now work quite well, and also putting a screen on the window to keep the bugs out. Honestly,you will be having so much fun hanging out with all your new friends, you will only be in the room to shower and sleep.
You can look at the Hedonism website, click on group events, and see which groups will be there during which weeks. If you book with a group, you will get a better rate. We have gone with Jon's Fluffernutters (fluffernutters.com) several times, and will be there Nov 10 - 18. The Fluffs are a great group, normally people of various ages, some couples and some singles, non-judgmental folks from all over, friendly and inclusive people who want to party and have fun, some nudists, some swingers.
You can make Hedo what you want it to be, and I'm positive your wife will not have any trouble finding a guy to play with. If you go with the right attitude, you will make friends that you'll stay in contact with for many years, and it may be the best vacation of your life. Feel free to ask more questions if you want and we'll try to answer. Good Luck!
