We have done the Atlantis sub in Grand Cayman and I do recommend it! You see the coral reefs and the big drop off where it goes down thousands of feet. Lots of interesting things to see.

You are sitting back to back in 2 rows looking outward through the windows. There are pictures posted on the inside walls over the windows identifying some of the fish that you will be seeing. There is running live commentary of what you are seeing and what to look for.

I would do it again.
