I was just posting on Facebook that it seemed AWFULLY crowded at MK for a 6! It was wall-to-wall people pretty much everywhere. Wait times were up to 3 hours for top attractions, and 2 hours for mid-tiers. Even the People Mover had a 25 minute wait (at least according to the CM I asked, the line wove out into the crowds it was so long, and I gave up after ten minutes). Heck, even Fast Track was taking 15-20 minutes!
Edited to add: Who is waiting 2-3 hours to ride a 2 minute ride? Space Mountain was 170 minutes, Peter Pan was 110, other top tiers were in the 2-3 hour range. Who waits that long??? Granted, there were no more fast passes, but still!
