Really its more towards a 4, but I have my reasons... which I will list below (wow, how convenient!)
I liked to location, the view, drinks, music... - however- the prices were a bit more than the already high "Vegas premiums", people congregate in strange areas due to an awkward traffic flow, which causes spotted dancing (basically just in tiny groups with your friends).
Definitely worth checking out, but not a final destination by any means.
