If you’re staying at any of the Disney hotels you can park at the rest for free (unless you valet). Also, even if you’re not a Disney resort guest, you do not pay to park if you are eating at that resort.
Supposedly there is a 3 hour limit, but we have parked at the Poly at 5 and gotten our car at 11.
You mention the GF, and I know they don’t charge for self parking, only valet. The downside is that self parking is across the street. All of the parking on the grounds of the GF are valet only. But whatever your choice, you must drive through the GF’s guard house lane before proceeding to self parking.
Just make sure you display your resort parking pass for any guard.
By the way, only the deluxe resorts have valet parking, all the rest are self parking only (self parking means free)
All resorts have self parking. On last thing to remember, EVERYBODY PAYS AT SWOLPHIN, guest and non-guest alike.
