I have to agree 100% on this.
However it's very inexpensive (relatively speaking) to change out some overlays than to build a new attraction.
They aren't changing the actual ride itself, just the scenery. It's a cheap way for them to send attendance at Epcot through the roof. I want to say 8 million less people visit EP per year compared to MK.
Disney is doing things on the cheap, the Little Mermaid ride is proof of that. I couldn't believe how bad it was and going back really made it stand out how pitiful they design was. I hear they have changed the lighting, so you can't see how bad of a job they did. I'll be seeing how that works out soon enough.
In any case, my girls experienced Disney more already than most people do in their entire lives, so if this is our last trip it's not like it's going to negatively impact us. The US/IOA/Sea World trip a few months ago proved we can have just as much some where else.
