My family took my 82 year old grandmother on this tour last summer and we all had a blast. The tour guides were really knew a lot about the area. We saw a school of dolphins and a lot of jelly fish. One of the guides caught a jelly fish in a net so the kids could look at it up close which was neat. If there is no dolphin sighted on your trip, they will let you go again for free. Totally worth the money spent!
