While it's certainly a nice place to visit (food options are great from the cheap to the mid-range 24 hour Wolfgang Puck to the super pricey Robuchon), staying in the actual hotel was pretty awful. Super thin walls, a sad little bathroom and dirty looking sheets are not okay.
The curse of the Vegas 4 star strikes again. The bell guy told me they were planning on renovating the entire hotel and I hope they do. MGM is classic Vegas and deserves more.
