For me The Mirage was a great blend of value and quality accommodations.
Location: Excellent. In either direction you can get to great attractions across the strip including the forum shops. In The Mirage you have good dining options for almost everybody's price range. Although there is not a big chain coffee shop there is a Roasted Bean that will suit most peoples needs. The Carnigie Deli is worth a try and the burger joint right before leaving the hotel is a good bet for some good American grub.
Room: For the double queen room we shared the digs were pretty nice. The accommodations were clean and modern. The bathroom and tub were good sized and the furniture was comfortable. For the $$ I was very pleased.
The only knock I have with The Mirage was the pool scene. It didn't really impress and seemed to be lacking energy. Maybe we happen to be there on an off day but I was pretty bored.
Overall I'd definitely come back. For this Yelper it's got everything I need for a price I can afford.
