I realize I haven't posted a lot, but I've actually been a member since early 2001 and a daily visitor. I figured I have to say something about everything I've read in this thread.
First, to all of us who absolutely LOVE Epcot the way it was/is. I can remember being 8 years old and remembering my favorite ride being Horizons, especially with the Orange smell. Also, we had a running joke among our family that the Caveman in World of Motion who was "blowing on his feet" was all of us at the end of a day at Epcot. However, I have seen the times change and with it the "interests" of Disney's audience.
I wish I could still ride those wonderful attractions, but the demographics of today's society are changing and Disney needs to change with them or they will find themselves wondering where everyone went.
My best example, when I graduated from High School in 1999, 4 of my buddies and I went to Disney World to "celebrate". While we were there, I had my first "Negative" Epcot experience. Not one person in my grouped liked it (except me). I couldn't believe it, this was the park I had talked to them so much about. What wasn't there to like? I now realize that it was because Epcot wasn't presenting anything "out-of-this world" to them. And likewise, many of the younger generation today feel the same way. Well, you could say, let them go to IOA or Busch Gardens and leave Epcot for the rest of us. The problem, these same people in 10 years will be bringing their own families to Disney. When my friends have families of their own, will they bring their family to Epcot? Maybe, but they will always remember from their first experience that it was "boring" and nothing special (I for one STILL DISAGREE with that)
Thus, it brings me to this whole idea of changing things at Epcot. As one imagineer said on a Travel Channel Special "it is harder to impress people these days". In order to insure that Epcot will continue to entertain guests into the far future, they need to present a new reason for "my generation" to come. Unfortunately, it seems that the classic omnimover rides just don't impress many people anymore as they did in the 80's/early 90's.
In my heart I will always have the fond memories of Epcot of the past, but I embrace the future and the potential changes that it could bring. I only hope that impressing people doesn't mean thrills. My challenge to the imagineers: Make an attraction that will blow the socks of even the greatest thrill seeker, but that a 1 year old can ride. Impossible you say? Remember what Walt Disney said (and the quote from Horizons): "If you can dream it....You can do it!"
