We have been snorkling for several years, so this year I wanted the family to get open water certified for scuba diving. I saw an article about swimming with the manatees for American Pro. After some research, we decided it was too late in the year for the manatees, although the folks at American Pro said they still have good luck.
Instead, we opted for the scuba program. For $249 each, plus tax, they will spend two days with you and get you certified. You must be willing to take a few weeks time before to read and learn all of the material in the dive manual. It takes a little effort, but it was worth it in the long run.
