They do not permit room charges here, which makes precisely zero sense since the entire thing is owned and operated by MGM Resorts which normally lets you room charge all of their attractions on the Strip. Worse yet, the bartender lied to me and said I could still receive points for my outrageous $25 per drink purchase by taking the receipt to the Mlife desk. (You earn 25 points per dollar spent, so that's significant.) The Mlife desk later told me that I was lied to and would not honor the points I would've earned from the $50 receipt.
So, in summation, poorly planned and operated to not allow room charges to half the Strip (and thus half their guests), and dishonest staff.
