The United States is indeed a country on wheels. Once you get off the plane, there are no taxis or subways; you basically head straight to the car rental companies. However, compared to my car rental experience in Europe, there are too many extra charges. Initially, I had already spent over 5700 RMB when booking from China, which claimed to include all rental fees, taxes, insurance, and additional drivers. But upon picking up and returning the car, I was charged an additional $344 for alleged various airport taxes and insurance. Additionally, despite returning the car with a full tank of gas, I was still charged around $60 for a full tank, even though locally filling up a tank does not cost that much. Returning the car two hours late incurred an extra day's rental fee plus tax. Moreover, they refused to refund me, citing that I was over two hours late. Well, if you don't have ample free time, I suggest you don't choose Alamo and try other options!
