Did you notice if the restaurants are really, really crowded but not the parks. We leave next Friday and I've got my fingers crossed (and toes, and eyes ) that ADRs are hard to come by due to the free dining plan only and not because everyone and their Mom is going to be there!!
The restaurants were crowded but not packed. We actually had ADR at Concourse Steakhouse for 6pm and I had in my mind 7pm so we got there at 640pm and we had about a 5 minute wait.
Have a great time.
