We took our 3.5 year old daughter, who gets scared easily. So all we said was that she was going to see fish under the water without getting wet. This boat is not a sub. She was excited waiting on line and eagerly descended and found a seat in front of a window. Everyone has a window seat and there is enough room to move around. The whole excursion is 45 minutes. We saw tons of fish. They have posters above the seats so that you can identify each variety you see. Lots of oos and aahs from all on board. Our little one loved it. The last 10 minutes you get to ride topside, great view and breeze. Well with the money!
