Valet parking at resorts

[Tiggerfan14]

hi, going to be in tampa for a few days and want to make the drive to disney for one of the days. I see you can valet park at the resorts. If I am not staying at the resort can I still valet park. Was thinking of parking at the poly and taking the monorail over to the magic kingdom. I know you used to have some type of pass to get into the resorts, not sure if this is possible. Thanks
