me & my fiance did the dolphins in depth tour at epcot on our november 2003 trip. it was great, you take a tour of the living seas, were educated on marine dolphins, got suited up in provided wet suits & went to the backstage area of the aquariums, viewed the dolphins, then joined 2 dolphins, calvin & rainer in the water with 2 trainers. you assisted in tricks, got to pet them & received a picture of your dolphin hug, one of our favorites. i dont remember if people were viewing us from the outside, we were too involved. afterwards we showered & watched a video, received a tshirt, info packet & our picture. it was well worth it in our opinion, we paid $110/each with a birnbaums coupon & we had a great time, we would do it again.
we also did the discovery cove in cancun on a trip, we spent more time in the water, playing with the dolphins at discovery cove. but i think the disney tour was more educational & informative.
