Great hotel room itself. Had some difficulty at check-in due to MGM staff confusion who told us to go to signature hotel connected to MGM which was incorrect, nothing to do with host. Tell MGM staff you have a booking at MGM (not signature if this comes up) and have them look up your name. Host was very friendly and responsive during this issue.
There is also a ~45 dollar resort fee due at check out on top of cost of stay and ~23 dollar parking fee per day. Some things to be aware of as additional fees not listed.
Overall, host and room was great despite check-in difficulties.
