For smaller groups or individuals, that can forego exclusive access to the facilities, we are offering a weekly public investigation every Tuesday. Tickets for our non-exclusive overnights will be $100 per person and offer the same hours and amenities as our standard overnight save for the check in guided tour. Non-exclusive overnights will be limited to a maximum of 16 people. Private accommodations with private bedroom and full bath are available for an additional cost. Check-in time is from 5 pm to 7 pm. Checkout time is noon on Wednesday.
