Has anyone used them for snorkeling trip and if so was it worth it?

Beth and I took the Aguaspace trip and had a great time. We enjoyed the sailing, cheese and crackers, fresh melon, and a nice snorkel excursion; as well as the cruise along Klein Bonaire watching through the glass hull! The glass bottomed boat gives non-divers and non-snorkelers a taste of what can be seen in the crystal clear Bonaire waters. We didn't see much that we had not on other snorkel outings, but consider the trip a good value. The crew and four others with us made it a most pleasant morning.
