Do they ever add tickets to sold out parties?

We have flights booked for 11/9-11/-12 for my daughters 13th bday. The Christmas party is sold out during those dates, do they ever add tickets after an event is sold out?

Not online, but occasionally people have had luck going to guest relations at the parks. Not guaranteed though
