Entry only or entry plus parking?
Choose entry only if arriving without a vehicle you will park inside. Choose the appropriate entry-and-parking option if you are driving. A rental confirmation is not a park reservation. Official reservation guidance explains that arrivals should be within the first 30 minutes of the reserved period and parked vehicles must leave by the end of their slot.
The source reviewed does not promise a daily release hour. Treat the 30-day date as the start of a booking window, not a guaranteed midnight ticket drop.

Plan the reservation before the rest of the day
- Check your visit date against current park notices.
- Decide whether you actually need to park before choosing a ticket.
- Save the confirmation and review the arrival instructions.
- Allow a buffer between this visit and any later timed activity.
The reservation planner works backward from your chosen date. It does not hold a slot, check inventory or buy tickets. Pair it with your car-days plan if this visit is part of a longer driving day.
