We went to Dolphin Adventure and did the dolphin signature swim and the sea lion encounter. It was an amazing experience, with a lot of interaction between the dolphins/sea lions and visitors. We found the dolphin experience to be spectacular. While at the place, they offered us a last minute deal for the sea lions. We took them up on their offer, and were really blown away by the sea lion experience as well. The staff are very professional, courteous, and it is a well run operation.
The main downside was the cost of photos--they wanted to charge $139 for a CD of pictures from the experience for two people!!!
