Me and my fiance are going to get 4 days down in the Key toward the end of September. Neither of us have been there before and would love some input on for our itinerary. We're more nature and adventure minded, not so much party. Some things we know we want to do is explore beautiful beaches, go snorkling, and possibly fish, but we're also up for suggestions.
Any must see's or must do's? I would say we have a small to moderate budget. We are willing to spend a little more if it's really special.
