Right at the airport, many rental companies are clustered together.

Very satisfied

Not bad, very good, no extra unnecessary charges

At the store, you can ask the staff if there are any available upgrades; they usually help you find one, which is great.

Terrible, terrible, terrible! I reserved the car a month in advance, but when I arrived at the store there was no car available. I had to wait 3 hours for them to get a car from another location, and then they increased the price by over 50% when I got there, with a 'take it or leave it' attitude. They even said that without immediate payment, they wouldn't hold the car. I finally got the car back to my hotel, and the next day it had a flat tire. No roadside assistance was provided, and I was told to handle it myself. After a lengthy discussion with the rental company, they suggested I change my travel plans, which was ridiculous since I already had my hotel and flights booked. This was a horrendous car rental experience; it felt like I was being taken for a ride!
