I'm staying at the MGM Grand for a couple of nights next week. I have never had a need to deal with the concierge and I'm not sure how helpful they really can be in my current situation. I have two tickets to KA ($99 face value seats) for one of the nights. My friend has already seen KA and would rather hit a club. Can the concierge at the MGM Grand help swap these tickets for guest list passes/admission to Hakkasan or one of the other clubs?
