The MGM signatures is quite a nice hotel. The 2BR/2BA PH suite was perfect for our group of 8. Manageable size plus a great view of the strip!
A few downsides were that the hotel only allowed one car to be able to valet at our tower so the other cars were forced to park at the MGM, which is quite far from the tower that we stayed at. Terrible wifi and cell signals also was an inconvenience.
Overall a great experience but I'm not sure whether I would book it again, just because I would much rather deal with the actual hotel when I need some issues dealt with, not a third-party company, in this case, Blue Chip.
