Assuming the photo below is accurate, it looks like they did it on 10/4, which may or may not have been hurricane related, depending on your definition of hurricane related. There were other parties after the hurricane and before this one that did not offer this option.
If they do offer it, it would only be at MK guest relations. When I bought a last minute ticket that first party after the hurricane I was told by DHS Guest relations that MK was the only place that could do it outside of the app. I was able to buy it online (in front of the CM), however I’m not sure how accurate that information from the CM was as another poster was able to obtain a ticket at Epcot guest relations that morning. Probably an issue of certain CM’s not knowing/ not wanting to do it.
Anyway, if you’re gonna give it a go I would advise going to MK in the morning, as there would likely be a very limited number of tickets, if any.
