WOW! What a deal and what find. Check in was super seamless. We arrived at 9am before our check in at 3pm, and the Signature staff let us check our bags with the bellhop, and simply gave us a pool key to relax by the pool till check in time. Fantastic! The main pool in tower 2 had drink service, and a limited food menu for us while we relaxed. We also had access to the main MGM Grand pool, and lazy river which is connected to The Signature by a long hallway with a couple of people movers. The walk only takes about 5 minutes. We loved this unit because of the upgraded hardwood floors. Not really a fan of carpet in Vegas rooms, so this was amazing! Bed was super comfortable. There is no room service due to Covid currently, but there is a starbucks, and a breakfast cafe within the Signature, also the MGM food court is about an 8-minute walk away. We will definitely be back!
