Definitely enjoyed our stay at Tower 1!
We were able to check in upon arrival (1 pm), leave our luggage with the bell hop and grab our keys before the crowds. We were instructed to wait until 4 pm to enter the room to allow the housekeeping service to complete. Unfortunately, when we went to the room at 4 pm, they still weren't done so had to wait for 30 minutes in the lobby. Note there is no daily maid service, but we never use it at hotels anyways.
Our room was homey, cozy and spacious - queen bed, sofa(bed) and dining table for two -- even had space for our inner tubes. Kitchen area had a microwave, large mini-fridge, one burner oven, blender, coffee maker (for ground coffee), along with plates, cups, utensils, etc. It was great to be able to save, heat up and eat our leftovers with real plates and utensils. The bathroom was also big, jack and jill sinks, separate toilet area, shower and jacuzzi tub! With all the walking we did, we used that tub every night which was clutch!
Tower 1 is conveniently close to the rideshare area and our average wait was just a couple minutes. Although the Signature had its own pools, we opted to go to the MGM Grand's lazy river. Pretty packed as we went on the 4th of July, but still so fun and relaxing!
Lots of dining choices on property. Went to a fast food pizza place, International Smoke and Hakkasan (highly recommended).
It is a bit of a walk to the MGM Grand entrance to the strip. But I'm guessing no matter where you stay in Vegas, you'll end up doing quite a bit of walking. However, once on the strip, we were relatively close to Target and ABC store where we bought water and snacks. Also depending on the length of your stay, you may need to buy additional shampoo, coffee, etc. so it was great to be so close to Target.
Just returned, but trying to figure out when we can go back!
