Thought I'd follow up and let everyone know how it went. The only place we had an issue was at Earl of Sandwich. They said they take Disney gift cards, but only physical ones. No problem using it at table service restaurants, including Teppan Edo. They did need to take my phone to the back, but they were back very quickly with it. If you have concerns about letting the phone out of your sight, I wouldn't do this. But it worked great and we had no problems.
