If you bring traveler's checks, make sure they are American Express. All they want is passport number, I carry color copies of passport--never a problem. Helps if power goes out, or phone lines--happened to us last trip. Belize bank ATM would not/could not give out cash, I guess phone out. TC paid for lunch, etc. Flashlight good idea--we take mini-mag lights--slip in pocket or purse. They also turn into a "candle" if power out. Yeah, zip locks bags! Half the clothes--you don't need anything more than tees and shorts, bathing suits (2 unless you enjoy putting them on wet, as things don't dry very fast in AC) I save $1's for months before, they really come in handy.
