I haven't read anything about the Las Vegas Hilton on this board.
Do any providers frequent those bars, casino?
How is Security there?

There is no security at the elevators. Don't know about the opportunities at the bars or casino.

I found no problem with security. I also saw few, if any providers at the bars, although I was there diring the week. Perhaps the weekends are better.

My suggestion - go with a sure thing and contact one (or more) of the many great independents in Vegas directly.

for bar action - the Mandaly, Palms or the Barge at Ceasers---

IMHO
