We were there this past Friday for the swim (booked independently of our cruiseship - which only offered the encounter). Only 79 degrees outside, and we all definitely used the wetsuits that were provided. We were on the 1:30 boat to Blue Lagoon (it ran about 10-15 min late), orientation, put on suits, break into your platforms (only ten per platform... there were three), and then the program.
Part One: In water the entire time for petting, hug, kiss (cheek and lips), 'dancing' by holding fins, and generic photo opportunity.
Part Two: The swim. Adults had a dolphin pushing on each foot. All I can say is WOW and it goes by FAST!!
Warm shower provided for afterwards in the restroom area. Hubby didn't want to do the swim so we booked him as an observer for $20 (included the ferry ride). We were back on the 4:00 ferry back, which first stopped at the ferry terminal on Paradise island and then it went on the the cruise ship dock (so all the cruise ship passengers just stayed on). Hubby was able to take awesome pictures from various places on the docks just above the platform - he took over 100. We still bought two from them afterwards (magnet pic $8 and a 4x6 in photo holder for $14). Definitely an awesome experience!!! But needless to say, there was absolutely nobody on the beach area of Blue Lagoon (you can see it from the ferry as you are arriving). We didn't even venture over that way. I hope to have pics updated to my webpage by the end of the week if you're interested. www.cmgoddard.com
The swim was definitely worth it!!
