In about three weeks I'm moving to San Francisco (Pacific Heights.) When I arrive at SFO, I'll have three bags and my dog. It will be a Sunday morning. And I'll want to rent a car, since my car won't arrive for a few days.

A few options come to mind:
1. Take a taxi and hope they don't mind that I have a dog. Ask a skycap to help get my stuff into the taxi.
2. Find a car service to meet me at the airport. I've been calling around and can't find anyone who says that it's okay to have a dog in the car.

The above two options would require me to rent a car in town. The Avis/Hertz places at the big hotels are open on Sundays, so it's okay.

or
3. Figure out a way to rent a car at the airport and get all of my stuff to the rental car.

Any suggestions?
