Made my reservation over 1 month in advance. When I got to counter, I was told that they did not have my requested size but I could pay more for the next size up. Turns out my car was sitting waiting the whole time. Despite locking in a rate with Expedia in advance, they informed me the rate would be higher since I was bringing it back 2 hours later in the day than the time I was picking it up. So they added that charge, then when I returned the car at the agreed-upon time, they charged me an additional penalty claiming that I was late for my reservation. Thankfully Expedia was able to straighten it out after 1.5 hours on the phone!
