Worst location I've ever been to. Last time i was there i was sent back inside 3 times to use a "coupon". The coupon was a $15 off discount FROM THE EMERALD CLUE WEBSITE! No choice of car and rarely (only 1 out of 6 times in 2 years) did they actually let me rent a fullsize.
It's almost worth flying into SFO and driving round trip when there's no chance of snow in the pass.
