Hello. The easiest parking is at Motor City Casino level 3 is casino floor three min walk from anywhere in the garage. If you aim to collect more than 3k at the window you will have to sign up with their Club Metro. MC kiosk will take large wagers, this time of year the lines won't be bad at the window.
MGM kiosks will limit wagers like even $100 it will deny you then your money is stuck in the machine. Parking is in a big garage then you ride an elevator to get to the casino.
Parking is an awful roundabout tower at Greektown, kind of a long walk and not easy to find the casino door.
Remember everything the casinos say is a lie "know your limits" "only bet what you can afford" sayings like this. they want the regular Joe's to lose $20 a day on crazy wild parlays so they lose $600 a month, meanwhile if the Joe would just bet $600 on one game straight wager he might actually win it. Enjoy it, what a blessing to have a fun night of action! Good luck
