Here is some guidance that I received when I was the greenhorn.
- extra pair of sunglasses
- flipflops / watershoes
- swimsuits (7 days = 4ish)
- sunscreen (1 spray can = 2days) extra available anywhere
- t-shirts & going out shirts - again extras available
- underwater camera (most will now take HD video)

Rita's last comment and extra deep breaths. (Island time is the same as sailing - all in good time) Sometimes the hardest thing to do is leave normal life behind.

Oh, and the last thing is extra money. You have come a long way to let a few extra dollars stop a good time.

Relax and have a great time.

Fair winds, Jim
