Crowd calendars are awful. Wretched. Trust them not.
Having said that, Halloween itself has been very light the past few years - but part of that was since the park was always closing early for a party (and people don’t want to waste tickets on early closure days). Now that the party is at DCA, it’s possible more people will show up to enjoy DL itself on the holiday... especially with Halloween Screams happening. So I’ll be curious how it goes this year.
