Standard parking and shuttle reservations can be made online or by phone up to 90 days in advance on a rolling basis. For standard, accessible, and electric vehicles, the majority of reservations are released 90 days in advance, and a limited number of reservations are released 3 days in advance. The 3-day-out release is intended to provide access for visitors who were unable to plan their trip further in advance. Booking a reservation far in advance is recommended.
