Well. Since Walt is cryogenically frozen maybe they woke him up for input on one of the newer attractions like RockN Roller Coaster, Test Track or Mission Space.
Seriously, I would guess Epcot itself would be the last thing that Walt had input, as the park itself is an attraction.
I like the EPCOT train of thought, since that was his brainchild. If we are looking for a specific attraction, how about Living with the Land, or Living Seas?
Granny, I agree with your observation that the EPCOT of today is not the same as Walt envisioned it. That's why I chose those two attractions, since they are the ones I think of as being most in line with his thinking, a working "Community Of Tomorrow".

PS There's good odds that I am still probably wrong, but at least I have a good story
Edit: Now that I see Kitnrose already posted the answer, I increase the odds of me being wrong to 100%
DJen - What about the shuttles from the MK resorts?
Oh, and Karen, I just remembered that Leigh Ann is there now, having just gotten there today. And, I read on another thread that she is sharing an Illuminations Cruise tonight with Kathryn!!!
No problem Karen ... we will want photographic evidence of course, lol.
Actually I am afraid the dreaded black monorial might pull up ... so I am going to give this key AAQ to Sandy. The fifth option is the boats from the resorts
