I highly recommend staying at Signature. It feels more like a deluxe condo than a hotel room but with the amenities of a hotel.
It’s is on the 3rd floor so there is no view but hopefully you are hanging out and not in your room. If you are going to be relaxing in the room, be sure to bring bubble bath products or buy some from Nectar Bath Treats in MGM Grand. The tub with jets was incredible.
Also be sure to allocate up to 30 minutes for retrieval of your car from valet at busier times. Most of the time they averaged 10-15 minutes.
