For anyone that uses the 2-day-free coupons from ParkSFO which previously required a minimum 4 day stay (which really means >3 days), these now require a minimum 5 day stay (ie, >4 days).

For 4 day stays you'll need to revert to the 1-day-free which has a minimum 3 day stay.

ie, their prices just went up by $17 for a >72 but <96 hour stay...
