Well where you should stay when you are in Las Vegas depends on a couple of things. It depends on what your budget is and where in Vegas you want to stay. I live in Vegas and there are many beautiful places to stay and some for a reasonable price. One of the lower end but very nice hotels in Las Vegas is the Stratosphere for only 30.00 a night and it is on the strip. If you are looking for a more higher end hotel to stay at while here, you can try either the brand new hotel that opens next week called The Cosmopolitan or the MGM Grand or even the Luxor! Have fun!
My favorite is Mandalay Bay for many reasons. Clean, beautiful, great food, awesome pool. I couldn't stand New York hotel...horrible experience. Loud coaster noisy. I like Treasure Island ok too. Excalibur needs a major clean up.
