Grand Slam Club - sail on all four Disney ships. Looks like several members here will be joining that club soon. Grand Slam Club Gold - sail on all four Disney ships in the same calendar year. Some are planning to do that. Have fun! Grand Slam Club Platinum - sail on all four Disney ship Maiden Voyages. Will there be anyone? And....my favorite.... Grand Slam Club Plus - sail on all four Disney ships plus the Big Red Boat. We'll be in that club early next year!!!
