While small and sorta hard to find, we found the aquarium to be a nice place to slow down a bit while still being entertained. We got to the aquarium right before one of the cruise ships were scheduled to disembark so there was TONS of people waiting for trolleys to take them to the pier. Made it a little stressful to find it and get in but once inside it was dark, and cooler. Starts off with a touch and learn center which my son enjoyed. Also had a huge area in the rear to feed sharks, and turtles, not to mention the wild fish who could swim into the holding tanks.
Pros: wasnt as crowded as some places can be in key west
Cons: small
