Have a couple of questions, so excited to redeem via myvegas: *night @ Mandalay Bay. Can we access the invited guest/VIP checkin line? *Zarkana *buffet @ either Bellagio or Aria. Not sure if 'free' option (for just me) or 2/1 purchase (DH didn't earn enough points) is slightly better deal, since not knowing if taxes are collected. With either buffet option, can we access the VIP line?
