We just got back last night from our time there. We were there Sat 9/16-Wed 9/20.
We didn't see any wait time over 20 minutes for any of the headliners with the exception of Dumbo, which always seemed to be an hour during the day. We waited only 10 minutes when we rode it at night.
Most FastPass machines were open. We had a FP for EE, and from the time we walked in the ride entrance to walking out of the gift shop at the end was 10 minutes, including ride time.
The popular restaraunts were booked solid, or only had seatings after 9:30pm. Saturday's Chef Mickey was booked solid, so was Sunday's 50's Prime Time Cafe, and Tuesday's 1900 Park Fare. We were able to walk into San Angel Inn on Monday at 4:30pm and get seated at a table on the river immediately.
We followed the Unnofficial Guide's least busy park plans when making our touring plans and avoided Extra Magic Hours.
I was very pleased at the crowd levels.
The longest we waited for anything was the Princess character greeting in Mickey's Toontown Fair. We waited 30 minutes because it seemed VIP guests were ushered in before us, so while the other character lines zipped by, ours crawled.
