I like MGM.
I stayed here recently and many times prior to that, and loved how easily accessible everything was. By that I mean the outlets are intuitively placed to make charging devices easier! The rooms are modern and I love the mirror in the restroom!
BTW, the VIP lounge is very cool. If you can get on that, do it. They offer snacks, and delicious coffee and computer/printer access.
It isn't as much of a labyrinth as other hotels and the rooms/towers are easy to find. There are a lot of eating options from cheap eats to fancy feasts. The arena is also nearby which provides the utmost convenience.
Pool area is cool. Not the nicest, but it serves its purpose.
Overall, not a bad hotel to spend a few days in.
