Obviously activities like this are affected by a lot of factors - like weather, other passengers, conditions out on the water. But the staff and crew of the Key Largo Princess Glass Bottom Boat take care of everything else! Everyone was friendly and professional. The boat is comfortable (great a/c and seating below - great views up top) and well outfitted with a bar, snacks, etc. We had a great time! The water was clear, we saw a fair amount of undersea life - and had the unexpected treat of being escorted back to shore by a pod of lively dolphins. While no one can guarantee that, I highly recommend this attraction! Nice way to spend a couple of hours out on the water!
