Accomodation: At the higher end, consider the Ritz Carlton in Dearborn (across from the Ford Motot HQ and near the Henry Ford Museum). Not too far from the cneter city, and very convenient to the airport as well. Weenend rates are a big bargain, relatively speaking.
There's also a Hyatt Regency near the RC (at the other end of the Fairlane Mall complex).
