My whole experience with Thrifty was horrible but the worst was the drop off at Charlotte airport. It says on airport but there is no sign for Thrifty at the rental return garage. GPS kept bringing me the same location. Called customer service and it took forever to get through to a person who told me it was on site at the Airport. Come to find out Thrifty and Dollar rental are owned by the same group and we were to drop off at Dollar rental. We spent almost an hour driving around stressed out about missing our flight. We picked up the car in DC and the agent was soooo slow. When it was our turn she couldn't find our reservation. Good thing I brought all of my reservation paperwork. Even with that she had trouble and kept saying there was something wrong with my reservation and the system would not let her get a car for us. The only bad part of my vacation was the car rental. Thrifty is terrible.
