I booked yesterday, I really want to go in August 2019 and stay at a deluxe and have a package deal with tickets and dining. Since yesterday was the last day to book without having to pay the parking fee when arriving, I booked.
Last year, prices for the following year came out in June. Previous to that, it was always August.
Yesterday, I was only able to book until July 2019 for room only. When the 2019 pricing comes out this year, I can modify the reservation to a package. Since package deposits are $200 and room only deposits are equivalent to 1 night rack rate of the resort you choose, I booked at an All Star resort and only gave a deposit of $165. When real package pricing comes out, I will change my dates and resort (Modify the reservation and keep the free parking).
