Service that my husband and I got in person was great! The morning we arrived we got out of the cab and our bags were immediately taken by the staff! We didn't even have to touch them. We were then told they would hold our bags since checkin wasn't until 2 or 3. We went to the front desk , got our keys and told us that we could call around checkin time to find out our room # that way we didn't have to stand in line at the front desk again. Reason why I did t give them 5 stars: we called around 3 to get our room # where the guy was rude and told us the \"main tower\". Walked around for 45 minutes trying to find our room!! Come to find out we were in the grand tower. The hotel is too big with disappearing signs. Our room was amazing as we booked a suite. Housekeeping always kept it extremely clean. We are going to stay at another MGM Hotel next month - THE Hotel @ Mandalay Bay and at Bellagio in Decemeber...we shall see which hotel is best for us!
