The Unofficial Guide suggests we arrive an hour before the park opens. However, the buses don’t start running until about 45 minutes before the parks open. ?? (We leave in NINE days. Yay!!!)
The buses start running well before the park opens. There are buses for early ADRs. For example we got a bus at 6:45 am for DHS for a 9:00 am open. This was from the Poly. Have a great time!
