Uber can definitely get you from Livonia to Ann Arbor. I would do a test to get an approximate Uber cost based on trying on November 16 game day vs MSU. Most bars tend to open at 9a or 10a on game day. You might call a few to see their game day opening hours.

There is a grocery store they can walk from on Industrial (I think is the name) - it is a Lucky Mart or something like that.

Probably not. They also don’t allow clear purses like the NFL allows. Only cell phones and a wallet or what can fit in your pocket.

The players leave their hotel on buses and arrive straight to the stadium - they enter thru the tunnel into the j. Ira Harris Locker room. You can only see them boarding the buses at the hotel or leaving the buses at the tunnel. In regards to the band I forget the name of the building where they start but it’s on Hoover and they march play down the street thru the blue lot and also to the tunnel entrance. Many people see them along the way and some follow them.

Opposing marching band does not attend games at Michigan stadium

Lots of them, and they are close to the entrances. You will probably have to book a spot.

we took a cab to ann arbor and then a cab back. If I had it to do over again.. I'd get to Ann Arbor early (two hours before game) and park on north side of central campus. Finding room is pretty easy and then you can walk around. Probably cheaper than two 15 mile cab rides.

The previous answers are correct although the alumni association also organizes tours on some Sundays following a football game. You could contact them to see if you can join one of those tours.
