New and "improved" ? I think not. Checkin is all self service. Shame on MGM , taking away a friendly and personal experience from guests to save a buck. It's easy enough, but for older folks it will be problematic. It's called HOSPITALITY- someone please remind MGM of their industry.
There is no one posted at the elevators making sure only guest can go to to the guest floors. Not very safe.
The halls in the hotel are sooo dark. Watch your step! And with no security you won't feel very safe here. I know I didn't. The rooms are a step up from a dorm room. Nothing spectacular, very blah.
Lastly, you can hear the rooms above and below you open and close their window shades. Not the biggest issue , but when the noise is so loud it wakes you up at 6:30am - it's a problem .
