My first trip to stay at MGM Grand was so full of disappointment we left after a few hours.  Long queue to register, our room given to someone else so we got downgrade in bed size with no upgrade in room, rowdy guests, near brawl in elevator over it being too full, elevator door attempted to close 3 times as a malfunction coming and going, room AC did not cool room, room fan not available or given upon multiple requests.  When we considered walking through to the pool we opted to just leave due to crowds.  After checkout we stored bags and went to event.  This was ok but at end of concert they closed bathrooms in order to shoo us all like cattle through the venue exit doors.  Appalling to not let patrons use the bathroom at end of concert!  We walked out in tiny cross legged baby steps grateful to be making our exit.
