Planning Notes
- Expect a later start than the hospital events because this one opens at 7:30 PM and wraps at 2:00 AM.
- This is a high-profile venue, so lock the date early if you want the active night rather than the sold-out one.
- Use a compact kit because the appeal here is moving through a large, unusual mansion rather than camping in one zone.
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 listing promises exclusive after-hours access to one of the most recognizable haunted mansions in the world.
Guests can investigate with Haunted Nights staff, with Winchester House guides, or on their own.
