Another alternative, if you have even the slightest interest in automobiles, is to skip both cities and go to the Autostadt in Wolfsburg. Book a room at the on-property Ritz-Carlton, walk to all the car-oriented exhibits, then treat yourself yourself to a great dinner in the RC"s Aqua restaurant - Aqua has 3 Michelin Stars and it was just announced last Monday that the restaurant won another San Pellegrino award as one of the 50 best restaurants in the world.

The ICE train station to take you to the city of your return trip is immediately adjacent to the Autostadt complex.
