How does the $15 f&b credit work? Do you charge to the room and they take off $15 off one charge per day? Any reports of it stacking multiple night credits for one day?
And I also know that you can charge to your room if you're dining at another MGM resort. Does the credit apply to these charges as well? i.e. check into Excalibur, walk over to Luxor to use the f&b credit.
