We enjoyed the Ocean Riders tour which incorporated several snorkeling stops near reefs and some near land. There is no place to use an actual toilet, but the ocean didn't mind the occasional pee break. If there is any chance that someone may get seasick, this isn't the tour for you... the fun and excitement of it all is riding the waves and cruising through the ocean, which is what my 2 teenagers enjoyed the most. We did not see any whales since we were there during the summer when they are not common, but we did see a school of dolphin (and rode along with them in the boat!) and our tour guide brought up an octopus for us to see and touch. Ocean Riders is very exciting and worth it!
