Stayed here 3 nights with a bunch of friends to celebrate some birthdays. Rooms were very nice and beds were very comfy. We upgraded to a panoramic view room an stayed on the 65th floor. Not worth the extra $$$. The view of the strip wasn't really that great. If wanna stay where their is a good view, I would recommend the Bellagio or someone more towards the middle of the strip.
The pool area is like any other pool but they have areas for kids only and one for adults. Heard the pool party is pretty killer but we didn't get a chance to go.
As far as food, the two deli shops suck!! Way overpriced. Roast beef sandwich + soda at one was $20. My wife had a $8 Tomatoe basil soup at the other. If you want fast food, I would recommend the food court across the street at the mall.
We did also eat at the Chinese restaurant Red 8. That was great! We had Pork Belly, Jelly Fish, some noodles and a veggie dish. Overpriced of course cuz they can..Its Vegas. But at least it was good..
Overall the Wynn is a very nice place. Staff is always friendly. Still doesn't beat Mandalay Bay only because they have a badass pool! Loved my stay though and would come back.=)
