The party will have special fireworks, a special parade, stage shows, character meet & greats, and party exclusive treats and merchandise. You can also go around to certain locations for free treats (cookies, pretzels, hot coco, etc.)! Regular day guests must leave the park by I believe 6 so the park will be far less crowded (theoretically). The closer you get to Christmas the more crowded the parties will be. The atmosphere of the parties is really amazing AND you can't miss the "snow" on Main Street! Just make sure you go in with a plan of what you want to accomplish and get out of the party!
