IMHO SkyPark has about the same level of service as PCA, but a few plusses:
- Indooor parking available if you want to pay a little extra
- Valet service
- Donuts (ummmmm) if you have a morning flight
They also have a rebate program, and a web coupon at

What I don't get is how come the lots to the west of the new International Terminal are still so expensive, and why SFO long-term parking has always been the most expensive and least appealing option of all.
