This hotel was nothing short of amazing. The best views; the best location;
and the best staff. It's clean; conveniently located to other restaurants
on the strip; although we ate at the restaurants on site and each was so good
there's really no reason to leave. Ohhh the views. The beach was free of seaweed; 
amazingly clean and plenty of space; it wasn't crowded at all. 
Stay here; you will not regret it. Did I mention how comfortable the beds were. 
Yes save yourself trouble and stay here. It's really perfect.
