These big crowds have created a parking frenzy in the area making AT&T Park parking a major headache for fans. The recent success of the SF Giants and commercialization of this area have both contributed to an increase in parking rates. During the 2012 World Series, some fans had to shell out more than $150 for parking.The SFMTA extended the hours of parking meters in the surrounding area and charge more during events. We created this AT&T Park parking guide (and map) to help drivers who are headed to the area plan ahead to save time & money.arking on game days is usually $20-$30. Plenty of people tailgate here and they even have porta-potties on-site which are a must have if you are going to be drinking. *GAME DAY PRO-TIP: Bring cash! Most privately owned parking lots will only accept cash so make sure you bring at least $40.
