There was nothing to dislike. The explanation of the trip on the website is extremely accurate. Our party of 6 people ranged from 4 years old to 67. Each of us had a special experience. The staff makes a big point to seat young people and large parties in the front of the submarine. It was very exciting for them.
If you go to Kona more than once per year, the Atlantis offers a $39 annual pass so that people can enjoy the submarine and the changing sights whenever they come.
