I stayed at the Encore Sunday through Monday. Based off the other hotels that I have stayed at on the strip, this would be one of the nicest I have stayed at. It is an overall very clean hotel, upgraded and beautiful. We stayed in the King Resort Suite which was really nice because we had the view of the strip, a sectioned off living area and large bathroom. They also have some really beautiful store in the hotel with a large selection.
What really disappointed me from my trip is the fact that the toilet was leaking from the valve and a good portion of the restroom was all wet. The other hotels that I stayed at didn't have this problem.
P.S. I would definitely recommend dining at Costa di Mare and watching the La Veve show.
