Planning Notes
- Guests are asked to arrive between 6:30 PM and 6:45 PM for check-in and the opening tour.
- Handheld paranormal gear is encouraged, but wired DVR camera systems are not allowed.
- This date is sold out, so use it as a signal that future Harriman dates may need early monitoring.
What Changes During This Window
These are the reasons this event is worth scheduling around instead of treating it like a generic date label.
The event copy describes the building as more than 160,000 square feet, which makes this a very large hospital investigation.
Haunted Nights says the investigation is free roam rather than sectioned into timed access blocks.
The source page includes drinks and snacks, which helps for a full-night institutional venue.
