What did you pay for the deposit? Was it a flat $200 or was it the equivalent of a 1-night stay?
Usually, a "room-only" reservation has a deposit equal to 1-night stay and the balance isn't due until arrival. However, over the past year there have been a lot of reports of room-only reservations getting booked as a "basic package" -- which has a $200 deposit with balance due 30 days before arrival.
