Has anybody here booked an MGM promo via the Royal Caribbean Cruise Line past guest promo that expires the end of the month? Jumped ship to the MGM after discovering it was only a few bucks more (after deducting the $150 resort credit they were offering) a night for Grand King vs the standard I had booked @ MC. Called MGM, operator not sure where I can use the credit within the resort. Was told "only in MGM...no other properties". When pressed operator said all hotel owned restaurants and bars should be included but not stores or gambling...but she had no idea which restaurants, other than the buffet, are included. You'd think they'd at least give me a list when I check in...anybody care to guess where it'll be valid?
