A lot better than the Finding Nemo ride at Disneyland for sure. I don't even know why I was comparing Atlantis to that. Actually I was able to get on Atlantis Submarines months before while recently I tried the Finding Nemo Ride. Nowhere as close.It was pretty cool going into a submarine. Our tour guide was funny, and I enjoyed my time underwater. There were several cool fish that we saw and even a shark!The boat ride there was equally nice because you could enjoy the super blue waters of Hawaii and you were able to see Diamond Head from the sea.Another bonus is that they give military discounts. But you'll have to buy your tickets at Outdoor Recreation ahead of time.Book the bigger boat!
