The Renaissance Center was built in the 1970s as General Motors' headquarters, and the building recalls its automotive history in a ground-floor classic car museum. A $100-million refurbishing in 2000 added a large glass atrium called the Wintergarden -- just the spot for casual dining, shopping, and riverfront views. The hotel sits in the heart of downtown adjacent to the People Mover and a food and shopping court. The comfortable rooms have all the expected amenities; those on the upper floors provide great views of the Detroit River and Windsor.
