Unfortunately, I cannot give this tour location any type of good rating. This was to be a very relaxing tour, glass bottom observation hull so that you can view the ocean marine life. The vessel is 30+ years old, the glass was in fact, plexiglass, that had seen its best days years ago. Only 15 minutes of viewing. We were to have time for snorkeling, but I was the only person in the water, this lasted 15 minutes, nothing left to do but sit on the antique sub for more than 2 hours, until our 3 hours tour ended. Upon getting out of the water, I fell on the slick aluminum body of the sub and bruised both legs, not good.
