For those of you with the DDE card and who use the free valet service, do you show them a receipt to prove you have eaten there? I was thinking it might be convenient to make a lunch PS but park in the morning to do a couple of hours. Occasionally, I make a PS too early and we miss it or too late and we end up eating beforehand. If I missed the PS and don't end up eating at the resort can I just pay the $6 valet fee after the fact? Thanks.
