We have decided to rent a car (rather than taking a flight or shuttle from Belize City) on our upcoming trip to Hopkins. Since we will have access to a car the whole time, we are wondering if we should venture out on our own for activities such as the Jaguar Preserve, Mayan ruins, cave tubing, etc. or go through a tour guide. We are used to being pretty independent travelers...we went to Costa Rica several years ago, rented a car, and explored completely on our own. Still we are not sure how road access/conditions are for some of the parks and sites we want to see. Thanks for any tips you can provide.
