Stayed at the Wynn Resort, once in June & again in August. Excellent rooms with great views, Red Cards for keys (which you use to accrue points at the casino), comfortable beds, double sinks, 42" LCDs you'll probably never turn on, service that makes you feel like royalty.
I LOVE the Wynn. Also, the casinos are amongst the best on the strip for their delicious ("complimentary" if you're gambling but don't EVER forget to tip) cocktails with the good kind of alcohol. Their mojitos are delish, the mimosas use actual orange juice instead of the icky syrup you get at most other casinos.
WIN!
