We are going on a cruize that stops for one day in each of these four towns. Looking for advice from anyone who's been there, as we try to decide what shore excursions to take, if any, or do we explore on our own? Aside from beaches and/or boat rides, are the towns themselves worth exploring, any particular sights we should not miss?
In Porto Belo, an option is a trip to Florianopolis, which would take the whole day - better than staying in Porto Belo?
Thanks for your help!
