Wynn is the best hotel in Las Vegas.
Vegas has been my party destination for the past 5 years and I go there minimum 7 times per year. After trying out hotels like the Venitian, Bellagio, Cosmopolitan I quickly found paradise and it is Wynn ;-))
We book the salaon suite room in Wynn which goes around $1000 per night, but it is totally worth it. You have a mini bar in your room, nice couches and they have frette luxy sheets... A hot tub in the bathroom and the room services comes multiple times per day.
Tons of restaurants and awesome bars in the hotel area, simply the best!
