I just spent a few hours at MGM Grand Detroit today... I thought it was a nice place... gave me that Vegas vibe. Thought it was a little funny that valet was free, but they charge for it in Vegas. I put a little over $8300 coin-in on slots and played blackjack for 2 hours at an average of $70 per hand. That all earned me about $75 in express comps and very little tier credits. I wonder if it will have any effect on MGM corporate offers in Vegas... anyhow, I had a good time!
