To elaborate on that (in case you don't know what that reply is referring to exactly)...... There is a Temptation Yacht that can be rented for a half-day that can fit up to 10 people. However, one can only rent it if they are a Premier member with Yacht privileges (not all Premier contract include use of the Yacht).
The tours desk at Desire Pearl is offering a small cat (6 couples max) nude booze day cruise leaving/returning at the Pearl dock - it's not regularly scheduled so couples must book in advance - both Pearl and RM guests are welcome to book. For any from Temptation you would have to make pre arrangements with the Pearl tours people and also get yourselves to and from Desire Pearl IMHO - Cost/fun wise the best overall value winner is still Steve's Boob Cruise
Thanks to all, unfortunately we arrive the day of the cruise (18th) and leave before the next one. Timing sucks.
Walk next door to albatross catamarans. They told us that they could arrange small group charters. We didn't discuss nude but don't believe that'd be an issue. The gentleman told us "whatever you want" a number of times in the conversation.
