The MGM Grand Signature is an awesome condo style hotel with excellent service and amenities. My family and I had a great time. The pool area and lazy river were a highlight as well as the seamless connection between the 3 towers and the MGM Grand hotel. We also appreciated the 24 hour gym and the valet parking. The staff all over the hotel are really friendly and accommodating!

The only issue I had, which it pains me to say, is with the host and her company. They put my reservation under the WRONG name, even after I communicated it clearly through our correspondence. The front desk couldn't find the reservation and it took over 2 hours to get in touch with someone who could help me. They also didn't send me confirmation numbers which would have made the situation avoidable.
It was an aggravating few hours during an otherwise wonderful stay. Overall I would recommend it just for the accommodations and staff, but make sure you get those confirmation numbers beforehand.
