It's an amazing dive, I think it's $140 per person, includes everything you need for the dive, all you need to take is a swimsuit and a prescription mask if you need one. From start to finish it takes about 3 hours. Everything else is provided, you meet outside Epcot guest relations, they'll ask to see your certification card and equipment sizes. They're quite good at guessing if you don't know. The tours start at 4.30 or 5.30
They take you on a tour of the backstage areas of living seas, then you watch a short video and have a briefing. They then take you to get changed, all your wetsuits and stuff is hanging in a locker with your name on it. They lock your locker keys away so your stuff is safe while you dive.
You then get taken up onto the gantries over the tank. Youre told not to go too near the dolphin section of the tank while diving and to not go near the section of the tank that's visible from the memo ride.
You then sit on a ledge in the water while they fit your tanks and BCD. You then get about 40 mins free diving time, you follow around the camera man for a few minutes so they can get footage for the DVD they try to sell you, then you can go off on your own with your buddy.
At the end of the dive they take your equipment (no having to wash your own kit) then you can go shower and get dressed. They'll show you the DVD they filmed and you can buy it if you want.
The price doesn't include park admission but both times I've done it theyve let us out into the park.
It's such a great easy dive, someone cleans all your kit, you dont have to worry about anything, no currents, plenty of fish, and half the fun is interacting with the guests on the other side of the glass!
Highly recommend it, and will probably be doing it next year again if we have the time spare.
Hope that helps!
