Many of the links to photos I've seen on here have pictures of strange-looking bugs: giant centipedes, multi-colored caterpillars, etc. I realize this is the tropics, but I wasn't anticipating much beyond mosquitos! Anything in particular to be on the lookout for?
Basically mosquitos and no seeums are the main issue. The no seeums are ankle biters and can happen at various spots. A little OFF below the knees are you are fine. Generally the bugs are worse right at sunset.
