in october of 2010 my bf and i attempted the 20 dollar trick at TI. I told my bf to do the sandwich but he chickened out, and just handed the man his two cards. He then held on to his wallet in the man's sight, playing aroudn with a 20 dollar bill peeking out of the wallet. we asked if there were any complimentary upgrades, and he gave us the top floor of TI which had taller ceilings and a more private floor seeing that you had to put in your room key to access that top floor. so it was worth it. we gave the man our 20 dollar bill as we were leaving and just said thangs ;D im heading out to vegas again on June 8, and am staying at vdara. I really want an upgrade.....so we probaby will try it. Has anyone tried it out at vdara? any tips? and how have you checked in early? is there ever an instance where you hand them the 20 dollar bill sandwich and ask for an early check in or "complimentary upgrade" and they for somereason CANT do anything extra for you? haha taht would be a waste....but i guess that's what vegas is? a gamble? ;D haha i would love to hear more :) thanks -T
