I really like the idea of moving this to EPCOT. That's a brilliant idea.
I think Carousel of Progress originated at Disneyland, didn't it? And wasn't it moved from California to Florida when Disneyland got rid of it to build something else in Tomorrowland there. So if it was moved to EPCOT then it would be the second time this was moved.
Everything with connections to Tomorrowland is fascinating to me because I bet if Walt Disney was still alive he'd be stunned that so much of Tomorrowland is still around and has not been replaced with more innovative things. I think Carousel of Progress was a great attraction in its day...but my family does not enjoy it here in 2012. This is one of those attractions I will go on while my family is off doing the rides that are too intense for me, such as Space Mountain. By the time they are done waiting in line and going on Space Mountain I typically have watched Carousel of Progress...so it's a nice chance for me to sit and relax and watch the little show while they're off being adventurers on the coasters. I admit that sometimes I even enjoy a little nap in Carousel of Progress since it gets so dark in there!
This could be a nice attraction for EPCOT, since that park is supposed to be more adult and less thrill-ride. Let the real estate occupied by Carousel of Progress be reclaimed for something more fast-paced. In my opinion, Tomorrowland should be geared for teenagers...a place with high energy that they can be excited about. Get a high-energy ride in there and make Tomorrowland a place that the teens want to gravitate towards.
It always felt like an "EPCOT attraction" that got installed in the wrong park by mistake.
