It is highly recommended that tickets to Monster Mash be purchased in advance either online or at Mystery NH Escape Rooms. Capacities in each half hour are limited so time slots may sell out. Tickets may be sold at the door only if there is capacity in a time slot.

For the safety of the performers and guests no flash photography or video is allowed to be taken inside the attraction.

There is no touching of the actors, customers, or props allowed inside the attraction.

You will experience intense audio, lighting, extreme low visibility, strobe lights, fog, damp or wet conditions, moving floors, special effects, sudden actions, and an overall physically demanding environment.
