I was there for my 50th in July and the nice restaurant private dinner was over $500, so if you eat at the nice restaurant (pre-book before you arrive) and do 2-3 activites a day plus a massage a day you will spend close to $1000 a day plus the room and private speedboat. This is a steal if you drink as everything costs a ton as it all has to be flown in.

Private message me if you want some tips
