We were suppose to the river tubing excursion, but we had skip Jamaica due to bad weather. We were going to take watershoes(required), sunscreen, bug spray, towels, and some cash in case we needed it for anything. I don't remember if the info said they had lockers to keep things in or not. Have fun, I was disappointed we missed out on this. My dh and dd have ziplined before. The place they did it, told them to wear gloves(work kind, not cold weather type) and they had to wear tennis shoes.
