Went to New Orleans for French Quarter Festival a week ago, and stayed at the Aloft Downtown. My option was valet - that's it. When I brought out the card to my 3 and showed the guy that checked the car in, he gave me the "Yeah, yeah - I know how it works" look.
When we left, the younger kid that was working valet walked away and 10 minutes or so later came back telling me he had no idea how to make it work. I said "Okay, if I just drive it out?" "Sure"
Yeah... That was the single tightest parking garage I've ever been in, and my 3 now has it's first booboo as a result. I've got curb rash on the back passenger tire, and I can't help but think if I'd explained to the valet kid how to use the card that I might not have it.
Also worth noting, they just taped something to my card so they could hang it up. I just looked at the card thinking "That better come off." (It did.)
