So I managed to find a grocery store that had the tickets for sale still, but once I got to the register the cashier wasn't able to actually sell them to me and said the machine was telling her to pull all of them from the shelf. So, I assume any grocery store that still has them out is an error and that Disney isn't allowing the sale of any tickets anywhere at this time. Am I out of options?
Most likely yes; I would think about booking a hotel stay at an on property hotel. That’s probably the only slim chance you would have that Disney might sell a ticket to you, but even that isn’t guaranteed... there just isn’t clear official information right now...
