I stayed here because quite frankly I am a Hilton diamond member so I like the extra perks and the night I was there the room was cost less than the dinner I had too so. The service was good, but the rooms are all scattered to hell and they have this weird numbering system. Traveling as much as I do I hate lugging my bags half-way to hell to my hotel room, at least they gave me a room upgrade which makes me want to ask what is their standard room because there was nothing really extra about it. They stuck me on the 7th floor instead of higher up and the walls are pretty thin.
I would say stay here for conventions if you can't get a room anywhere else (because your company is cheap) since it literally next door to the convention center, you are here on a budget, you are old enough to have watched Neil Armstrong walk on the moon, or you are super touristy and its the middle of summer and you have go to Vegas for some reason.
Otherwise my stay was fine, the decor is super dated but it was clean and the Hilton beds are always so comfy.
