Hi... First response under new name
We (2A/13 and 12 yo) went to Disney World 07/26 to 07/29 2013 (a park a day) and we planned our days based on EMH.
So whichever park had the EMH, we went there that day.
On our first day, we went to EPCOT. Yes, there were a lot of people at the entrance. But once the gate busted open (8am), people just scattered throughout the park. We went to Soarin' first and waited about 5 minutes. Then we walked across to Mission:Space and got to ride that back to back. We still had plenty of time to walk around. One negative thing though was that the WS didn't open until 2 hours later. There was a lot of time to kill.
On the second day, we went DHS. Again, a lot of resort guests at the gate. But once opened, we just went all over the place. We were able to get through TOT with 5-minute wait. After that, we got FP for it for later time. Then we waited in line for Aerosmith ride... We waited a little bit (30 minutes?). While in line, people started to pour into that part of the park. Then we went back to TOT. The reader didn't read my card (during entry) so we walked all the way back to the entrance to get it activated. So we did all this in the first hour. Then we went to Toy Story Mania and got FP for late afternoon return.
On the third day, we went to MK. But the EMH was in the evening. There were a lot of people... TONS. But we immediately went to the Fantasy land and there were no one. We were able to ride Dumbo and had light meal at Gaston's Tavern. There was still very little traffic.
On the final day, we went to AK. We got up a little late so we didn't make it to the EMH (after 9am). Once we got there, people had already started to enter the park. We were able to grabbed FP for EE and had a light breakfast in Africa. Then we went on EE. Then people started to fill up.
All in all, yes, it was very busy in all of the parks. But I think that's a part of the Magic... being around others. I believe that may have been one of the peak times to go. But we enjoyed our times. We didn't rush into doing anything... just went with the flow. Fortunately, we were able to do what we wanted at our pace.
We talked to a family on one of the buses... They highly recommended us to download Touring Plans as it would help us plan our day. To me, that seemed to be stressful as we would have had to go all over the places. I had the Disney Experience app with me but I barely used it.
So go to the World and enjoy it. Don't stress out about the times and crowd (as we also did).
ENJOY
