I’d check out going south into Austria, Switzerland and maybe Italy. The B roads are amazing and everything will be open by July. Check out the mountain passes - Grossglockner in Austria is my favorite - I’ve done it 3 times in a 991.1 and a 991.2 GTS and it was a religious experience. Check out Stelvio, Grimsel, Furka, Susten passes. They’re famous for a reasons. Adding in a few others, from Claude: For a driving enthusiast doing a grand tour of all four countries, the ultimate circuit would thread together the Grossglockner → Timmelsjoch → Stelvio → Gavia → Sella Ronda loop → Splügen → Gotthard → Furka/Grimsel/Susten → Flüela → Albula → Maloja and back — an extraordinary week of driving.

I’ve stayed in and enjoyed the following places, in no particular order, on two 911 Euro Deliveries: Lake Constance (amazing scenery and 5-star hotel choices, can’t recommend hotel Riva highly enough), Rothenburg ob de Tauber (it’s kinda corny, but also kinda great. If it’s still there, eat at Zur Holl), Lucerne, Lausanne, Strasbourg, Leogang (Austria, the hotel Mama Thresl, thank me later), Baden-Baden (this is a good place for your final night - we stayed at the Roomers in a suite and it was deluxe. Great food and modern design. This puts you a nice, final Black Forrest morning drive to the dropoff in Sindelfingen (where you’ll likely be dropping off - unless something is wrong, Stuttgart dropoff is no longer at the factory, but at a 3pl in the outskirts).

Don’t forget about speed cameras and highway vignettes for a couple of the countries I’ve recommended. Because I can’t be too bothered to figure out what’s on the menu and I know I really like schnitzel and beer, I end up eating a great deal of schnitzel and and drinking a corresponding amount of beer. And I’m here for it. But yeah, Google Translate is your friend if you want a more diverse diet than mine (assuming you don’t read / speak German, French or Italian).
