I agree -- the Osborne Lights at MGM are amazing and overwhelming. We also love to go around to the various resorts and look at the decorations, which are customized for every resort. There are really special displays made out of chocolate and gingerbread at all the deluxe resorts: a giant gingerbread house at Grand Floridian, a chocolate African village at Animal Kingdom Lodge, a chocolate amusement park at Boardwalk, etc. If you combine it with a meal at a resort, or even just looking at the animals wandering around AKL, it's nice, relaxing time.
