The new fab-rooms are nice. The laminate floors make it feel clean, which may have given them bonus points. And we ended up with a room facing the strip so the view was pretty good... could kind of see the Bellagio fountains from the window. The bed was probably the best I've slept on in a hotel. Not as good as home but damn decent.
Downsides include the noise. Noise from the street isn't terrible but it is audible. Until the air conditioning unit kicks in, then that noisy bugger is what you hear.
While we're talking about the air conditioner: it drips water. I'm going to assume it's like the compressor on your vehicle dripping condensation... or else I'm going be really grossed out by what dripped on me.
The bathrooms were not renovated when the room was. Wallpaper was peeling. The chromed fixtures were rusting. The fan didn't work. The shower head had crappy pressure.
