If you like mid century modern you will love the Plaza or if you have an affinity for The Tendrloin in San Francisco you will be thrilled, In other words good luck.
Have i stay at worst places, yes; even in Vegas.
That said unless you have to go downtown for a meeting choose someplace other than Vegas to go.
However, if you do go, hang out in Oscar's for happy hour; it has a great view of the Street People. Actualy the drinks are good, service in the bar gets better the more times you go and the appetizer selection is decent, try the prime rib sliders.
