There is a lot of stuff in the world. You generaly don't need to take it with you everywhere. But here is a list of stuff you will want to take with you on your trip to CASA XIPE TOTEC.

A swimsuit and a good towel. You have read the Hitchkikers guide haven't you?

A good pair of walking shoes and sandals.

Snorkel gear. We rent some out but it is always better if it fits you like it should.

A flashlight. Neccessary for walking at night.

Acidopholis pills. Good to take anyway. Start taking them a week before you leave.

Sunglasses.

A good book or three.

Citronela bug juice. You never know. Bugs own the world.
