We use this perk often (mostly at the GF). I agree, the valet folks are now asking that you tell them in advance that you are a TIW cardholder and they will put a special parking ticket in your car so that they know upon return. We used it 3 times in May and yes, they asked to see the receipt and card every time we returned from dining. They don't care what you buy, as long as your have a dining receipt from a restraurant at that resort. Also as mentioned, if you are a resort guest, you may STILL charged on your hotel bill, so check prior to checking out of your resort. This happened to us 3 times in the past. We now remove our resort parking pass after we go pass the guard. There is a barcode on it and no matter how many times we would tell them we had the TiW card, it would be scanned and put on our resort bill. Well they don't do it to us anymore, as we take our resort pass with US now. If they do charge you, your front desk staff can take it off your bill, but you have to have your dining receipt, so don't lose it!!!
