The Signature at MGM is a bit of a walk from the strip but it's great for privacy and you can still access the strip by walking through the pedestrian bridge and shops that connect the Signature lobby to MGM Grand's lobby (about a 10 min walk). The property was clean and the beds were comfortable. The sleeper sofas were less comfortable but similar to other sleeper sofas you would get at any other hotel suite.
Some things were a little out dated - DVD player instead of smart TV with access to streaming services, washing machine handle was broken so inoperable, and while most of the lights worked, it was a little dark.
Overall, great stay and still cheaper for a group than getting individual rooms at a hotel.
