Seems the biggest were on signature dining meals and merchandise. People would crow about getting several hundred dollars in savings on a trip (obviously take that with an entire block of salt).
I do agree regarding the digital media aspect. People complain about having to pull out their phone, and punch a couple of buttons, but it doesn't seem any more difficult than pulling out your wallet, fishing out 3 cards (CC, DVC card and ID), then putting it all back when you're done. I personally prefer my wallet to stay in my pocket. There's a lot more in there that I'd rather not have fall out in the middle of a theme park. The phone is a locked brick if I lose it.
