The hotel itself is not 4 stars, but the value is. I have gotten rates as low as $50 and just for location alone its worth it! Not to mention that the casino is not half bad, easy to navigate from/to your room & they have Carnival Court (an awesome and fun outside bar)
You can't go this cheap on the Strip anymore, maybe Sahara & Strat but they are waaaaay on the North side, can't walk it to the fun stuff on heels or in the heat all day... Also maybe you can get these kind of deals from Imperial Palace but that place sucks big time, the smell, its dark, cheesy and just boring.
