Last year, S and I accidentally found out that we could get free parking as long as we carpooled! Good thing we brought two of our friends with us, because the free parking was for groups of 3 or more. Well, I just made a quick phone call to a few garages, and the same deal is happening:
1 hour free - 3 persons
2 hours free - 4 persons or more
This is valid for the following parking garages (there may be more, but I was only interested in the downtown garages):
Ellis-O’Farrell Garage
123 O’Farrell Street
415-986-4800
Fifth & Mission Garage
833 Mission Street
415-982-8522
Sutter-Stockton Garage
444 Stockton Street
415-982-7275
Union Square Garage
333 Post Street
415-397-0631
