Detroit/Ann Arbor
Hotels:
Range from $109-159. Downtown Detroit would be more central to most of the activities, but also a bit pricier. I got one group price for the Detroit Marriott at the Ren Cen. [link] Their rate was $149/room. They would waive the room rental fee for the prom space if we spend $4000 on food and drink.
The Troy Marriott is used to conventions (it’s where our annual convention is) and our rate for that con is $89/night, but that con is like 500 people and takes up most of the hotel, so I’m not sure they would give us the same rate. Plus, a little out there from most of the attractions.
Ann Arbor would be more difficult to book and quite frankly, it's a cute little college town with stuff to do, but I think we'd have more fun in Detroit.
Public Transport :
If we’re in Downtown Detroit, the public transport is decent. The People Mover (elevated train) goes to most of the major attractions. I’ve not had experience with the buses or taxis down there, but walking is also good.
Eating and Drinking :
Downtown Detroit has Greektown and lots and lots of food everywhere. Also lots of bars and the Best Irish Pub not In Ireland. Downtown Delux, Town Pump, Hockeytown, Chelis Chilli, Old Sheleighleh, Cliff Bells
Shopping :
Not a lot of shopping downtown save some touristy crap.
