There is a food tax on restaurants that are part of a hotel, but nowhere else. And, rum is cheap, milk is expensive. Oh, and sunscreen applied often. A waterproof camera is fun to have while snorkeling. Some folks say to spit into your snorkel mask and rub it around with a finger to keep the mask from fogging up. We use Sea Drops instead, as my wife thinks spitting in your snorkel mask is gross...lol Have fun, and post a trip report afterward...
