I was there last week too and crowds were extremely low. Walked up to Cinderellabration within 10 mins of it starting and stood in the 3rd row, without 3-4 feet between each row in front of us. Walked onto Soarin, Tower of Terror, etc.
The good (park) restaurants were booked as far as walkups were concerned, but I also was able to score great times calling for reservations the same morning, so be sure to call from your room and give it a try, rather than try to walk in.
