If you book room only and want to change to a package, the room only will have to be cancelled/refunded and a package booked, requiring a new $200 deposit (or payment in full if done 45 days or less prior to arrival) as money paid toward one cannot be transferred to the other. A room only cannot be converted to a package by just adding tickets and dining as the two are separate reservation systems and cannot go from one to the other without cancelling and rebooking.
