My husband does not want to book an excursion and would rather "roam around" on our own. Personally, I think the idea of just roaming around a foreign island with 3 kids is not a great idea. We've never been and I think he assumes it's like Nassau with lots to see right off the boat. I'd like to have a few suggestions/ideas of things we could do just in case the roaming doesn't work out. I know about the Turtle Farm....any other suggestions?
