The receipt process is new, but in recent years they've been largely arbitrary about the extent they're going to harass the AP holders. Sometimes the wave you through, sometimes they scan, sometimes they scan and ask for ID.
I've complained about similar behavior to save 40 cents on a soda or to get a 17 cent button at Food and Wine, why should parking be any different?
I'm sure people are borrowing Annual Passes (or have been in the past) but the extent they're going to stop it seems silly. It's like the RFID chips on soda, removal of flexibility options for Fastpass+ that has to be booked 30-60 days in advance, or the $10 fee for a missed reservation that was made 180 days in advance. At some point they need to look at each of these problems as things they did to themselves.
Annual Passes - put a picture on them. It shows up at the entry gate (like Disneyland), it shows up when scanned at parking or at a kiosk where someone wants a discount. Also, forget the rule that the credit card has to match the annual pass if the individual is standing right there. You're being difficult for the sake of being difficult.
RFID chips on Soda - The amount of installation/infrastructure costs here was greater than $0, the frustration and dissatisfaction that arises from guests being nickled and dimed because some free soda goes out the window seems petty at best.
Fastpass+ - This one could be 6 pages long, but a hybrid of MaxPass and Fastpass+ is the way to go. 1 advanced booking per day for resort guests (and say a set # per year for AP holders). When you check into a park you get another Fastpass+ and you can always hold two at a time whether you use the kiosk or the app. Same day availability improves, the Tiers go away and you've kind of solved the "I have a fastpass for a nighttime show" problem.
ADRs: 60 days MAX please.
