Ladenburg is a little outside of downtown Heidelberg, so we assume you’ll be doing a decent amount of driving. If you intend to use Ladenburg as a starting point to discover the city and its surroundings, rent a smaller ride. There’s nothing like a compact for maneuvering into those narrow parking spots. Alternatively, if you’re moving away from all the hustle and bustle and bright lights, reserve something with a bigger engine and more room to move. Not many visitors regret spending that little bit extra on a full-size or a premium car.
