Question on theme park parking and Swan

[disneeeyfreak]

Hi. We are going to be staying at the Swan and I understand that I can get into the theme park with my room key and will not have to pay the parking fee. However, we plan to be at the park when the gates open and really do not wish to waste our time stopping at the Swan to register and get the key.
Are we able to show the attendant at the gate our confirmed reservation for the Swan or can we pay the parking fee and then be reimbursed?


Thanks.
