We were there and it was very crowded. I decided to judge how crowded the parks were by how long the lines were to the bathroom, ha! Actually, we were at Test Track at 11 AM and the fast passes were gone. I met another Mom in the ladies room and she said they got there at 10:30 and they were gone then, too. The stand-by line waits were 4 hours (240 minutes) for Test Track and Mission Space at 11 AM.
We were at Epcot from 11 - 8:30 PM. We only rode Maelstrom in Norway via FastPass. We did enjoy a wonderful lunch at the Cantina in Mexico and had PS at 4:45 at Marrakesh in Marroco. I'm certainly glad we had PS because people were being turned away in droves. We arrived for our PS at 4:30 and didn't get seated until around 5:15, but didn't think that was too bad considering the crowds. We, too, got stuck in Mexico trying to leave the park at 8:30. It took us 20 minutes (like another poster said) to go the distance in front of the Cantina. Once past that, tho, the crowds were manageable. The DJ's and music were great. Wish we could have hung out longer but we just couldn't fight the crowds any longer with our 3 children.
We would do it again, tho. As DVC members, we hope to someday stay at the Beach Club Villas or Boardwalk Villas and do it again. It would be so much nicer to be able to walk back to your villa, than wait for a bus, etc. on such a busy nite.
