Hi, I went to Dolphinaris last week during my cruise. It was an ok experience. We got to hug and kiss the dolphins but we didn't exactly get to swim with them. We just stood on a 4ft deep ledge in the pool and the dolphins came up to us and interacted with us. The trainer was leading the encounter and we were not allowed to swim out in the water with the dolphins. It was really interesting and fun to see the dolphins but I don't think it is worth the price.
Plus, during the encounter, there are photographers taking your picture, and if you want pictures of your experience, be prepared to pay. For 3 pictures it is $69. For all the pictures and a DVD it was upwards of $350. This is where they rip you off. They know that people will want the pictures, so they take advantage of that. Its a scam in my opinion and kind of ruined the whole experience for me. I wished I had gone to Chankanaab.
