Happened to us last month. We had 5 ADR's we ended up canceling more than 24 hours in advance, and we were charged $10 per person for each one of them. I'd like to think it's a technical glitch, but even if it is, that doesn't give me a great deal of faith in their systems. I'm not sure if it was here or somewhere else, but I read somewhere that Disney's whole computer infrastructure is very antiquated. They have a very slow website and we've all seen how glitchy
MDE can be. I think it's just poor IT all the way around.
