You will really only need PSs in November for the really hard to get places like Cindy's for breakfast (and getting that is a feat in itself). We usually only book PSs for places we would be really disappointed to miss out on, or when we're absolutely positive we will be in a certain place at a certain time. We've just got back from a trip. The parks were really busy, but we were still able to get in everywhere we wanted, either as walk-ups, or by phoning on the day itself or the day before.
