Review for Casino Grand Prix - Vilde Review For Casino Grand Prix - Vilde Google User Apr 14 '14 at 21:21 Be aware of thieves in their casino! I just came back from staying at this hotel. Although the Mandalay Bay is a nice hotel, my brand new cell phone was stolen from me in the casino. The security in their casino was absolutely no help and supposedly could do nothing for me. I'm pretty sure there are video cameras EVERYWHERE in the casino. You couldn't at least attempt to help? So disappointing considering that they are a very costly hotel. I go to Vegas frequently and Mandalay Bay is no longer an option for me. View full site to comment or like
