Hi Lilliam! Welcome to
my very own corner of planDisney, and thank you so much for stopping by with your question.
First of all, I'm so sorry! I can imagine how frustrating it must be to already have four
Mickey's Not-So-Scary Halloween Party tickets and realize that you still need one for your husband.
Unfortunately, if October 16 is currently showing as sold out, that really does mean that there are no more tickets available for that party date. There isn't a secret or separate inventory of tickets available through Guest Relations, Disney Resort hotel front desks, or at the
Magic Kingdom ticket windows once an event has officially sold out.
Mickey's Not-So-Scary Halloween Party is incredibly popular, and October dates in particular can sell out pretty quickly as Halloween gets closer. Disney limits the number of tickets sold for each party night, and once that capacity has been reached, there isn't a guaranteed way to purchase one additional ticket.
That being said, I wouldn't completely stop checking! While I absolutely don't want to give you false hope or suggest that additional tickets will become available, plans can occasionally change. I would periodically check the official Mickey's Not-So-Scary Halloween Party ticket page or call the
Walt Disney World help center to see whether availability happens to reappear for October 16. Just keep in mind that you should plan under the assumption that the date is sold out unless you actually see a ticket become available for purchase.
I also wouldn't recommend purchasing a ticket from an unofficial third-party seller or another Guest. Special event tickets are subject to Disney's terms and conditions, and I would hate for you to spend money on something that your husband ultimately couldn't use.
Lilliam, I'm keeping my fingers crossed that a little bit of pixie dust comes your way! In the meantime, keep checking the official website occasionally, but unfortunately, there isn't another reservation system or hidden ticket inventory once a Mickey's Not-So-Scary Halloween Party date has sold out.
Warm hugs,
Ana Paula
