I'd like to echo Mike W.'s comments and add my own. I've done the dive quest tour two times in the past two years. Its a lot of fun. Note that the dives are in the afternoon. One at 4pm and one at 5pm. You do not need to purchase admission to EPCOT to go on the dives. You meet on the far right gate and wait for the tour guide. They will ask for your c-card and then size you up for gear. The gear is new. you get your life support gear and a shorty and boots. Water temp was about 70 deg. I've not had an issue with weighting. They seem to hit right each time. I would recommend bringing your own mask. Those you used the provided masks complained about leaking. you can also bring a dive watch or computer. The experience begins however with a back stage tour which lasts about 20 minutes. you then head to the locker room where you will find your own gear bag. You do have to enter the exhibit area and interact with guests on your way to the top of the tank. They will give you guidelines on how to interact with guests. For this experience, disney considers you a 'castmember' to you basically have to smile and wave a lot. I mentioned the gear above, but forgot to mention the tanks. They are small, about 50 cubic feet. I've never come close to emptying my tank. If you do, no problem, just head up and they will give you another one. Bottom time is 40 minutes. At the beginning of the dive you have to stay together and then one by one, go into the diving bell where of doff your reg, smile for the cameras, don your reg and exit. This takes about 15 mintues for a large group. After that its free swim where you can explore on your own. Its fun to interact with the guests especially those in the restaurant. When the experience is over, you do have the option to purchase the video for $30. After that they release you into the park. this is great because you get 1 or 2 hours free admission (assuming you didn't purchase it) before the park closes.
