We just returned from 2 days at Universal (Nov 5th and 6th) and the crowds were pretty low. We had express passes because we stayed on-site, but we would have been fine without them. The longest wait I saw was 25 minutes for Despicable Me. We rode Escape from Gringotts one evening at about 6:15 and only waited 5 minutes! I had originally planned for 3 days in the parks, but we did everything we wanted in 2 days.
