I was wavering on which rental agency to use, and researched them well. Alamo seemed like the least problematic. Turned out that was true - they may have been a few dollars more, but I got to skip the line and got in and out of the rental facility in about 10 minutes. The car (Nissan Altima) seemed pretty new, about 1700 miles on it and ran flawlessly. We went to the Grand Canyon and Hoover Dam with it. Returning the car was even easier - drive in and hand over the keys and we were done! Definitely would rent from them again.
