If your going to party, temptations or hedo would be for you, if your going just to find a easy vacation hook up, then neither resort will be much fun. Attitude at these resorts is key. Singles who go for some preconceived notions thinking they are just nonstop sex fuelled orgies leave very very frustrated and disappointed.
Repeating what Sunchasters35 said as guys don't hear the first time. Views are great, Sex can be available when you less expect it, BUT a positive, non-creeper attitude is key at Hedo (nude) or TTR (topless). If you get labelled as a "creeper", news travels fast and your "out".
Check into the Boob cruise, and if u decide on it, then try to book it early in your trip. Friendships are often made on the cruise and can last the rest of your trip. Plus they are a lot of crazy fun .
