I did this in 2019 and loved it. Fun, informative, not stressful (I wasn't sure how comfortable I would around the dolphins - it's definitely not an issue, they're incredibly friendly and the cast members make everyone feel safe and welcomed). It's exotic to be in the water at EPCOT and you get a "behind the scenes" experience going into the Aquarium, locker room, etc. The photo you get with you & a dolphin in the water is one of the best I've ever gotten at Disney World. It's a fun break in the park day. I highly recommend it.
