VIPs, high-rollers, and guests of the casino spend the night at The Mansion, MGM Grand’s ultra-luxurious villas tucked away behind the main hotel. Sure, you can book it, for upwards of $5,000 a night, but the more fun way to get in is to get comped. The reported going rate for a free room here? Gaming in the casino with over $500,000. No big deal.
