Sure, you can do Hamm without a rental car. But with loads to check out here, having one would certainly make life easier. If you want to get out of the city and into the countryside, book a rental car with a bit of power. A full-size or mid-size SUV will take you to the area’s rolling hills in comfort and style. Rather spend most of your getaway right in the city? An economical, small car is a good choice. Maneuvering through narrow streets and squeezing into tiny parking spaces will be less hassle in one of these.
