The couples massage is a must do. We did it last year and were just there and did it again. It is worth the money and an experience to remember with each other for sure.
Really not all that sensual........but sorta depends ............ Our suggestion is to find a "like minded" couple and do a couples massage exchange......wow this has been a great starter activity for us!
If you are looking for a real actual massage then the blue tarp on the beach is the way to go. It was $45 when we were there July 2013. We did the sensual one and it was interesting, but not $200 interesting.
For us the couples massage was so hot and the one thing we still talk about now. It doesn't beat the third year anniversary Boobs Cruise trip - which was so wild! - but the massage was worth the money
