Room Only can be cancelled at least 6 days prior to arrival day in order to receive a full refund of the deposit.
For package, this is the language

from the website:
If the reservation is cancelled, amounts paid, minus cancellation fees and other amounts owed, will be refunded. For a cancellation made 44 to 6 days prior to guest arrival, there is a cancellation fee of $100 per package, plus any cancellation fees assessed by hotels or other suppliers. For a cancellation made 5 days or less prior to guest arrival, there is a cancellation fee of $200 per package, plus any cancellation fees assessed by hotels or other suppliers; provided, however, that for a cancellation of a Grand Gathering experience add-on option made 5 days or less prior to the experience date, no refund will be given.
Guest will be responsible for any cancellation fees assessed by an airline. In the case of a non-refundable airline ticket, the cancellation fee is equal to the entire ticket price. Cancellation of a refundable airline ticket must be made at least 1 business day prior to guest departure.
Vacation insurance is nonrefundable. Upon any cancellation, the charge for vacation insurance will be added to the other applicable cancellation fees.
