There are glass-bottomed boats, and then there are glass-bottomed bars—which is what the Pilot House marina in Key Largo is. Sure, it may sound like a novelty, but it's hard for guests not to stare at the amazing aquatic life swimming below them and their cocktails. If the fish aren't biting, the floor—which features more than 30 reinforced glass panels—is equipped with a number of fish feeding tubes, to get the frenzy started. Tired of watching Nemo and friends? A dozen flat-screen TVs and regular live music are also on the menu.
