Heading to Vegas on short notice and I am taking my g/f for her first time so i want to show her a GOOD time. Do things like http://vegas-passport.com/product.php?productid=1 really work? Should i get ahold of my concierge and se what he can get me in without wait on such short notice? Or is there a better way to go about this? Be out there this weekend (July 10th n 11th)
