We will be arriving at US/IOA early in the morning.Although,I know the Royal Pacific room will not be ready for check-in,will we still be able to register and pick up a "temporary"room-key that will allow us FOTL access for that day?
I've been able to check in at 6:30 am and have the room ready for me. It is upto the registrations from the previous night and how early you get there to determine if you will get into the room early.
They will give you the room key and let you enjoy the day at the park. They will tell you to check back later to get your room number. Each of your keys will be already encoded with your room information and you will be free to go directly to the room.
