Thanks for the room upgrade! We were originally placed in the old west tower but after our group showed up, we were moved to the Grand Tower side which was supposedly newer, upgraded and nicer. Yes, it was newer and nicer on the Grand side.
Pros: Nice employees, nice rooms (loved their double automatic window shades; no sun light comes into the room in the mornings), tons of fast food and sit down restaurants, nice pools (salt water pool too), a friendly crowd/patrons at MGM, easy access from Las Vegas Blvd and to and from the I-15. Easy check out. Free fast wifi in your room.
Cons: SLOW, VERY SLOW, valet parking. Even though I called down from my room, it still took 15 minutes after I checked in downstairs.
Like any decent Vegas resort hotel, MGM is nice. Decent rates, they have special events there as well. MGM is a big property.
