I love the idea! Maybe instead of changing the game map, add it to the winter cabin. It will be a train station outside where you can hop in and sit at, take photos, and hang out. To start it, you go to the front of the train and hold the grab button. It will go around the cabin in a circle, and if your character gets on the tracks and gets run over, it will respawn. poof! If there are no more players on the train when it is moving, it will automatically pull to a stop.
