Since most rental car prices are fairly similar brand to brand, I went with Advantage because their "compact" vehicle was most similar to what I drive at home.
I was originally quoted $279.45 for 4 days and an hour. On the day I was supposed to return the car, I knew I wasn't going to make my 1:30 return time. I called and spoke with Ian (didn't want them to think I was going to run off with the rental!) and he assured me it would be fine.
Upon arrival, Tony S. helped me unload my baggage and then Ian helped me get checked back in. My final price ended up being $242.52. Any time you pay less than you're quoted is a plus.
