I always love staying at the MGM because of its awesome location on the strip and because of its clean, modern design.
I stayed in one of the Stay Well suites this time. It boasts amenities like blackout shades, aromatherapy, air purifier, and vitamin c shower.
The aroma therapy device didn't seem to be very powerful, you could only smell it if you out your nose right in front of it. The vitamin c shower didn't feel any different than a normal one, and I didn't really notice a difference in my skin or hair, but it's hard to tell.
Two things are a definite plus about being in the Staywell suite:
1) there is a separate check-in at a private off-lobby lounge. We were immediately helped and didn't have to wait in the massive line with everyone else
2) free admission to the spa and sports center, which usually costs $25 per day.
The spa facility has two saunas, locker room, relaxation room and massive hot tub.
Cheeyeah!!
The pool at the MGM is also really great. There are 5 different pools including a club (which I have never been in) and a lazy river.
I will always come back to the MGM but probably not specifically to the Staywell suites.
