THe 7 hour tour is much better because it includes Epcot and MGM as well as MK. The first time we did it, it was actually 8 hours! That included the Reedy Creek fire station though. Once we had lunch that was a bag lunch of sandwiches and cookies and fruit, but last time we had a nice lunch at Momma Melrose in MGM. That was 2 years ago. Must be time for us to do it again! Yes, it does change. We saw some things the same, but each time we have done it, we have seen new things.
