Nice park; $10 a car to enter even though we were going there for the glass-bottom boat tour. The tour was average; in fact, they warned us that people get motion-sick staring down into the tilted windows of the bottom of the boat. I didn't believe this would happen to me, but I found myself stumbling outside and sucking on peppermints (they handed them out) with an unbelievable amount of other passengers who didn't believe it would happen to them, either. Also, I kept looking for their beach...until a staffer informed me I was on it. Their 'beach' area is tiny, rocky and coarse. Not someplace I would want to snorkel off the beach. A guess this is endemic to Key Largo's beaches; that's why they have snorkeling trips to take you far out. As my husband couldn't swim, we missed out. All in all, a little boring, especially considering how far in advance we had to show up to buy the tickets to reserve our space on the boat.
