We did it in San Antonio. It was GREAT!!! We had a nice buffet dinner and the food was pretty good as well as the cakes for desert. Then, we all lined up in front of the spot where the whales can slide up on. You can't touch them but you are REALLY CLOSE! The trainers are there to answer any questions and to tell you about the whales. We loved it! Next time, when my son is older I want to do the Beluga Encounter. You get to be in the water with them!
We loved Dine with Shamu, the food was very good (as good or better than a Disney buffet IMHO) and seeing the whales up close and hearing more about them was great. It was the highlight of our boys trip.
