Not being able to get a reservation in December, for the summer, is part of owning a 'floating' week. If you don't plan your vacation 10-12 months in advance, when the new buildings open, you probably won't get in at all unless you do an II exchange. The Marriott has far too many units, especially at the Surf Club. You'll be happier at the Ocean Club. Having elbow to elbow people around the pool and getting up at 5am to get a palapa, is not my idea of vacation.
