Looking to rent a boat in Sanibel for a day to explore the area and outer islands, swim, and hit some beach bars. Can anyone offer any tips on the best place to rent a boat and suggest some places we should go? Cabbage Key is one option we are considering and it looks like there are some good beach bars on Captiva. We are experienced boaters with a boat on Florida's east coast, but have not been to this area before and would need to rely on GPS to get around. Thanks so much.
