I honestly can't see how ANYONE can be bored at Moon Bay. The entire attraction of staying at Moon Bay on Key Largo is that it is about 1/2 mile from the world famous John Pennekamp underwater state park --- home to the most beautiful coral reefs in all North America!
People from Japan, China, Europe come to see them either by snorkely or the plentiful glass bottom boats that depart from John Pennekamp state park daily.
If you were bored at Moon Bay you did not do your homework! Also there's jet ski and boat rentals up and down the highway that access the Florida Bay in the back.
The pool itself is nice - and there's teenis on the grounds at Moon Bay. Now how can someone stay here and be bored? Our kids were 10 and 13 and we went back when they were 20 and 17!
