Very easy process to check in with an RV. After completing the check in with security, you will be directed to go to the reception station to register.
There you'll be given a form to complete. You'll need to provide your ID and choice of payment. Once your transaction is complete you be given a hang tag to place in your vehicle.
Process took no longer than 5 minutes.
Then drive over to the designated area for RVs and pick a spot and enjoy your stay.
