The Signature at MGM has a number of condos that are owned privately and managed by LSI (Luxury Suites International) . We had the worst experience we've ever had with any accommodation and our family has traveled a lot.
We had two rooms booked through Expedia with LSI and upon check in and getting to out rooms. it was like they weren't even cleaned, lots of hair in the bedsheets, dust everywhere, spider webs, pills on the floor, a package of cigarettes left in the nightstand. Dust and hair balls in the bathroom, toothpaste on the walls, honestly the most dilapidated, dirty set of rooms we've ever come across.
You can only connect with someone at LSI reservations by email after hours and a response wasn't not until the next day. They said they would "offer" another cleaning that would happen before 3pm. So purposefully we made sure we stayed out of the rooms for the day. Come back at 4pm to find nothing had been touched. They then showed up at 5pm just as we were getting ready to go out for dinner. The attendant agreed to come back first thing in the morning before noon. Once again nothing was completed. We lost complete faith that anything was going to be done, so I checked into another room through MGM and for our final day. The room was spotless and perfect in every way.
I will never make another booking through LSI, Expedia should vet these operators better, this felt like a complete scam, The rooms were outdated, damaged, showing terrible wear and filthy.
