I haven't been receiving cancellation or confirmation emails this morning. I only got 1 email confirmations out of all the cancellations and confirmations I had. I've never had a problem receiving them either. It's happened to me once before with a Raglan Road cancellation too.
But if you do end up making another Raglan Road ADR, I recommend going through opentable. I showed up for my ADR made through the Disney site and they couldn't find my reservation. Thankfully they believed that I had a reservation (I offered to show them my ADR confirmation number but they didn't want to see it.) but I did have to wait a while. I've heard of the same thing happening with other people before who made Raglan Road ADRs through Disney's site. I have no idea why that happens?
