Last year was an outlier with so much pent-up demand. In years past I don't recall it selling out so quickly.Comparative to where they sold out last year, they are actually running pretty far behind. I think most dates will sell out, it’s just a question of when.
Just my take, but the busier Disney is the faster the dates would sell out![]()
In 2019, I recall buying the tickets a few days ahead of time for mid-October party.
Selling out 4 weeks ahead of time still seems pretty brisk. If they price it too low it would also sell out faster, but then you are leaving money on the table.
