We used Budget last year and were very satisfied, however the counter guy was a little bit of jerk. My SIL was attending the National School Board Conference, so my DD and I accompanied her and her DD. The car's reservation was in her name (since she was being reimbursed). When I told her not to get the extra insurance (she wasn't going to drive any at all, and I'm covered by my own insurance), the guy kept warning her to remember this was on her credit card (because of the reimbursement), and if I wrecked the car, she'd be responsible. Since I work for the school district, I had set the reservation up as corporate, and we didn't have to pay for the extra driver. I had documentation, but nobody asked for it.
I searched everywhere for the cheapest rate, because the girls really wanted a convertible (preferably a Mustang). I got a rate with Budget for less than $250 for a week including all taxes and fees. Since Budget has primarily Ford products, I was reasonably sure of getting the Mustang I requested (which we did). Pick up and return was very easy. I loved being in the airport (before I had always rented off-site).
