I reserved a standard size vehicle for a weekend wedding I was attending. When I arrived (which was late so my fault) they were sold out of Standard Size vehicles even though I had reserved. However, they upgraded me for free to a small SUV and even though the online system only let me do a 2 day rental they changed it one day because I would be only out one day technically and dropping off after hours. Everyone was very nice and they all greeted me when I walked in the door and made this process very smooth. I was able to get out on the road and make it to the hotel in time for the wedding even though I was already running late because they are very proficient in what they are doing.
