I'm heading to Vegas for a girls' weekend at the end of July. It's going to be hot, hot, weather! Staying at the Encore. We're 30ish. Would anyone know of a club or lounge, of an upscale sort that might suit us best for a Thurs/Fri/Sat night out? I'm aiming to avoid the masses of 21 year olds that swarm some of the mega clubs. Any experience from others in our age category?
