Hotels
A few guys are staying at the Hampton Inn in Belleville. One is at the Red Roof. A bunch are staying at the Candlewood Suites off I-94 in Ann Arbor.
In each groups, there was one or two people with a car. The Hampton Inn *might* have a shuttle, but there are people with car. Important for lunch or to do other stuff.
One guy is staying in a crash pad near DTW, for about 20% of what everyone else is paying in a hotel. If you have friends at NWA or Airlink, have them look for you in DTW.
Like nosewheel said, Betty will give more information if you need it.
