Nice hotel choice in Detroit
There aren't too many good hotels in downtown Detroit. This is the best choice we've found so far. The rooms are reasonably large, well appointed and modern in style. The upper floor rooms have nice views either towards the high rises or towards the rest of the city. Note that the hotel is in a separate building from the casino, connected by a skybridge. Other than a little signage, you would never know this was a casino hotel. Free parking and free internet. The buffet breakfast is not expensive but I found much of it not very flavorful. 
An unfortunate note on Detroit. From this location you will often take cabs, depending on where you are going. This last trip, we took cabs twice and neither time did the driver use the meter so one is at their mercy for what the charges are. You have to either insist on a price or on the meter being used. But on a positive note the Detroit Institute of Arts is wonderful, the Fox Theater amazing and the Detroit Zoo one of the best in the US, noted for its humane approach.
