I always fly to Vegas. This time we're driving. Where exactly is the Aria valet? I know it's somewhere in the loop limo/cabs drops you off. Is it in front of the lobby? On the other side of the loop where you wait to get picked up? Which lane do I need to be in? I'm sure there will be signs. I just like to be prepared. "Failure to prepare is preparing to fail." Also, who do I tip? Is there only only one guy helping you? Or, does somebody open your door, another guy gets your bags, while another guy gets your info... Thanks.
