The Mouse Dining alert is still working. I have an email from 3:35 this morning showing multiple party of 2 options for Coral Reef Lunch on 12/7 and the reservation booking pages pull up when I click. When I search the website or app it shows no availability. Anyone who doesn’t have what they want should give it a whirl, it’s free. Don’t know if the other dining alerts are seeing the same phenomenon, I would think so.
