Hi Teresa
You shouldn't need much at all really, especially if you have already paid for your diving. Did the pre-booking include the boat trips as they tend to charge around ten dollars per boat trip so you may need to add that on and then there is really just tips for the room boy, your waiter in the restaurant and maybe a couple of dollars if someone helps with your luggage at the airport or on the seaplane.........other than that the only things i can remember spending on were a couple of photo albums from the shops and a couple of bars of chocolate! Oh, and if you have a spa on your island you may want to treat yourself.
All extras will be added to your room though and can be paid for at the end of the holiday by credit card - including the boat trips and any extra dives etc......
