We paid for our drinks,etc at the time so did not have any extras to pay for. It makes it easier to check out
When we were there we preferred to pay cash in US$ at the restaurant but i.m sure you can give them your credit card which they will just swipe as security then charge your incidentals to your room then settle your account on checkout.

I am not sure. They took an imprint of our credit card when we arrived and said they would put $100? $200? on it for incidentals but they never ran it through. When we checked out they charged us only for what we spent, which was about $20 at the pool bar.
