I haven't sleep in a car since I was a student and its something I don't want to do again, but Schloss Hotel has turned it into a luxury experience.
Directly on the shore of Lake Lucerne with its own private lawn and direct access to the lake, this luxury Hotel has 35 rooms including 7 junior suites.
One suite is more unique than the others as behind the doors of room 276 is a full sized pearl-white Jaguar MK 10 from 1963. The double bed is integrated within the Jaguar and the room also includes lake views and views to the mountains of central Switzerland through its large panorama window, also a whirlpool bath and ensuite with shower.
The hotel is well equipped with indoor pool and sauna, roof terrace and six other junior suites each with their own style.
