MGM offered me 3 nights comped in March, which I accepted. I made the reservation for a 4 night stay, with the last night at the casino rate. A VMB post here alerted me to March dates for the MGM Bonus nights. One of the nights available was my arrival night on my original reservation. I purchased the reward. When redeeming it, and making the reservation, the clerk stated the MyVegas reward is for a West Wing King room. The MGM comp offer is for a Grand King room. I'd rather not move during my stay. Are the rooms that different? Should I attempt to upgrade the WWKing room on arrival? Any input or suggestions are appreciated.
