Our daughter went a few months later and got lots of insects bites. You should carry a good repellant and a mosquito net for sleeping under. Particularly on the Carribean side where there are incidents of Malaria. We took preventive medication before leaving on our trip. One last note.
Theft is a major problem.
Take no valuables with you. Always keep your money and passport with you and in a secure place. We carried pouches that hung around our necks. During our month there numerous things disappeared. Nothing critical, though.
