We will be returning to our favorite island Jan. 1-8 after a ten year hiatus. Very excited! Staying at the Marriott. We're hoping to do things like tour the aloe factory, rent jet skis, go parasailing, do the catamaran trip, etc. Plus we'd like to do some nice dinners out. Do we need to arrange these activities and dinners in advance or can we arrive and see what we're in the mood for? Thank you!
