Are you booking a package or just a hotel stay? When I called to make our reservation, I originally wanted just a hotel stay. We would have had to pay one nights deposit, which was really expensive since it was a two bedroom villa. The CM told me that if I booked a package, I would only have to pay $200 deposit I believe. He said renting a car or booking the shuttle from the airport would qualify as a package. I thought we would have to book an excursion, but I was wrong. We needed a shuttle to and from the airport anyway, so it worked out. You just to pay the balance in full 30 days prior to your trip if you book a package. If you book hotel only, I think you can pay the remaining balance off anytime up to the day you arrive. Anytime we had extra cash, I would just call and make a payment. Hope that helps. But call and see. Every time I called the CMs were super helpful.
