I always wanted to stay at The Mirage, and I finally did on my last visit. It's not the nicest hotel I've ever stayed in, but it's still pretty nice. The regular rooms are a very decent size, are modernly decorated, have nice beds, all the TV/WiFi stuff, a big bathroom and an acceptable shower -- all things I look for in a hotel that I'm paying over $100 on a Tuesday night in April (aka, more than a lot of other hotels in the area).
I LOVED their pool.
The bars here were also cool - I really liked the look of Revolution; The Beatles bar that is in the casino, but we didn't have a chance to check it out.
We did brunch at their in-casino buffet, and it was just okay too.
