JUST DON'T! The rate is great - but there is a reason why - they overbook. I made my reservation six weeks in advance so it's not as if they didn't know I was coming. I booked an SUV but the only car they could offer me when I arrived in Phoenix was a tiny car which wouldn't have even fit our luggage. No other rental car company would honor their rate so I was left at the airport without a car. Their rental agent offered me nothing and she couldn't have cared less that I was left without transportation. I will mention here that I am disabled & it was 108 degrees when I arrived in Phoenix so I couldn't exactly walk where I needed to go. Live & learn - BOOK WITH A BIG COMPANY WITH A LONG/GOOD REPUTATION as there is a reason for that. I ended up next door at Alamo who had plenty of cars....
