We had a fantastic time staying at the MGM Signature. There was a slight hiccup with the check in process, but Charles and Petra were available and quick to make sure we were taken care of. The room was much bigger than expected, extremely clean and had everything you could need - from extra soaps and towels to a partially stocked pantry! Plus, it's located on one of the PH floors, which is a nice perk. Our room was in Tower 3, about a 10 minute walk to the MGM proper, but there were cabs available outside the lobby of our building 24/7. Highly recommended!
