Obviously, MGP earned during the event can be spent on the rewards available year-round. You can also spend it on home versions of the various minor attractions from the saucer, if you’d like to play Cuff-a-Cur in the privacy of your own chambers and/or apartment. Those special decorations will only be available during the event, so you’ll want to get the time in now so you can enjoy those furnishings – or the other rewards of the Saucer – for the whole year.
