Stuttgart, Germany

The Mercedes-Benz Museum and the Ludwigsburg Royal Palace are just two reasons to meet in this storied German city.

This city in southwestern Germany is best known for its auto industry (Mercedes-Benz and Porsche are headquartered here) and its verdant wine country, which produces fine Rieslings.

Attendees can experience each firsthand at the stunning Mercedes-Benz Museum (which hosts groups of up to 310) and the Museum of Viniculture (which accommodates up to 180 for visits and tastings).

Other regional attractions include exquisite castles like the Ludwigsburg Royal Palace, and charming villages, such as Esslingen.

Among properties for groups is the newly refurbished Steigenberger Graf Zeppelin, with 155 guest rooms, 11 meeting rooms and a Michelin-starred restaurant.
