MGM signature is a great hotel-like experience at a lower cost point than staying directly on the strip for the same value. However, the room wasn’t ready at 4pm when check-in is supposed to be 3pm.
Fortunately, there is a 3rd party service for the owners of these properties that was able to get us in a room of another host because none of us were able to get in contact with this host.
There was some confusion with then getting our bags from tower 1 to tower 3 with the room change, but it was eventually sorted out.
Outside of the check-in issues everything else was fine.
