Ha....SFOG wouldn't even sell me one down there...and claimed that season pass parking was only good at the park where purchased. I've since confirmed that is NOT the case...
I sure hope this parking situation is fixed by next year...but fear that it will be, as in Premium Season Passes include admission and parking to all SF parks (except where SF does not own the parking lot) and sells for a price comparable to Cedar Fair's Platinum Passes (currently $150).
