Last minute Halloween Party tickets?

Does DL hold back any tickets for MHP? Missed ordering them online.

I can’t speak to DL, but at WDW they do NOT hold any back (other than some they may hold back for VIPs, CL concierge desks, etc.). At WDW there are frequently still some tickets available “day of” - especially for the earlier dates - but none specifically held for at the gate purchases. So far there have been 2 WDW sell-outs; one was for a few days ago and the other is for Oct 31st. Most of the last week usually sells out as time gets closer.
