You can stop by the Front desk at any time to pickup a room key. That's the only way to get one. So you could go directly to your room when it is ready and then on your way to a park just swing by the Front desk to request a room key.If we just go straight to our assigned room when we get there, then will we get the card that acts as a pass? If not, then we may be better to go to the front desk upon arrival.
To get a RFID park ticket for in-park use you will need to stop by any Guest Service window at the park entrance.
