I am a big fan of Avis everywhere I go, but I wouldn't recommend it in San Diego. Took me 30 min to get to the rental building because Avis seems to run less number of buses from the terminal pick up. They won't stop once they leave the bay, so make sure you catch one. My reservation specifically picked a car, but when we get there, they said sorry we don't have that car. They Chev HHR. They wouldn't offer free upgrade to large class. HHR is pieace of crap, a coffin on wheels - literally. Windows are small, and controls are messed up. The doors were scratched up and interior were dirty. Remote control didn't work. Go to Hertz or Enterprise if you are in San Diego.
