Dinner at California Grill at the Contemporary Resort. It can get expensive quick, unless you're doing the dining plan, but it's well worth it. If you go, ask for Walter as your server...he's amazing.
My 2 fav resorts are AKL, and Poly. Just being immersed in the environment is wonderful.
As for attractions...see the parades and fireworks...also the Lion King show at Animal Kingdom.
