You can go to the rainforest for about $15pp per day, no massages are included. The new Spa Villas range from $199 to $589. There are many massages to choose from in a wide range of price. I dont have a price sheet, but I think a massage would start at about $75 & up pp.
You will also pay for any adult beverages, pictures from Shutters, drinks at any of the bars, Palo if you book that...
