Penngrove is a few miles out of central Petaluma, so we assume you’ll be doing a good amount of driving. If you want to use Penngrove as a base from which to discover the city and its nearby areas, book a smaller car. Nothing beats a compact for maneuvering into those tight downtown parking lots. Alternatively, if you’re moving away from the bright lights and traffic, reserve something with a bigger engine and more room to move. Not many travelers regret spending that little bit extra on a full-size or an SUV.
