There have been a few times over the years that I've been going to Disney that their posted hours were changed by the time I got to the park. I learned to live with it, and never trust the hours posted on the internet. As for the current change in hours, Disney genreraly plans their days so that you can see most everything in the park if you get there at open and stay till it closes. If there is nobody there, there is no reason to keep the park open late. I still remember when I used to skip highschool and go, the park would occasionaly close at 6pm, but it was empty during those days so I was still able to ride everything without waiting in lines. I was at the park on Saturday and all of them were just empty! I didnt wait in any line for any ride at any park. I parked in the front row of both MGM and Animal Kingdom because so few people were there. If tourism jumps up again, and the parks get crowded, disney will re-adjust their hours to allow guests to enjoy everything, but as it is now, be thankful! I'd much rather ride everything as much as I want without waiting in line, and close 2 hours early, then wait in 3 hours of lines over the course of the day, and stay at the park later! Besides, Epcot is always open untill 9pm, just buy a hopper ticket and spend your last few hours of the day, thats what I always do.
