The resorts are more gradual. MK needs to do the changeover so they are ready for the parties (first one is Nov 8th I think), but the resorts will be fit in around the theme parks. Basically over the span of the time between the first
MVMCP and the first Candlelight (or whatever the first scheduled event is at Epcot) they will flip everything over. They need to be quieter at the resorts, and usually have to maneuver things like the parts of the trees at AKL/WL/GF around the various parts of the hotels, so may need to work slower/more carefully.
