If you are planning to park on-site then yes, I would advise you to pre-purchase a parking pass through Park Jockey. Rates will definitely go up if you buy the same day you park. Another option is to park in a Pasadena garage operated by Parson’s. From there you can take a shuttle to the stadium. Good option if you want to hang out in Pasadena before/after the game.
