OK. A few quick thoughts.

- Drop your worry about "high floors". Nearly every good strip hotel has high floors with good views.

- I love the Wynn, but not sure if I'd stay there alone. I'd rather then be in the middle of the action (more so anyway). Venetian has more going on inside the hotel property. It's huge. Wynn is a quieter more upscale feel imho. As I said before, the Bellagio has the best location and a great feel to it, but better as a romantic couples thing.

- If you're young and want to party hard, consider the Hard Rock. Loud and small casino, but it's a world unto it's own.
