Resorts worth seeing include BC, YC, WL and AKL. You could get a boat from Contemporary to WL, do BC & YC as a wee break from Epcot (via the IG).
Sleigh rides at FW are fun, or for a cheaper version the wagons. You can’t pre-book the wagon rides and I’m not sure how often they run. The sleigh rides though can be booked 180 days ahead, so may be booked up.
