Keep the route realistic
Tegernsee, Achensee, Garmisch-Partenkirchen and Füssen are popular destinations from Munich. For a weekend, a clear main route is usually better than too many stops.
Estimate total mileage before enquiring and allow for detours, parking and spontaneous side trips.
Check vehicle and rental terms together
The Porsche Macan combines long-distance comfort with manageable dimensions, but driver rules, deposit, mileage package and any cross-border permission still need to match the trip.
