It is the oldest, darkest, deepest, quietest, and largest suite room in the world – 220 feet below ground, in the largest dry cavern in the United States that took 65 million years to form. The room is 200 feet wide, 400 feet long with a 70 foot ceiling.You take the elevator down 22 stories underground to the room which is completely furnished with all amenities one would need – two double beds, living room with a queen fold out sofa, (room sleeps up to 6), a library of old books and magazines such as a National Geographic collection dating back to 1917, dictionaries and other books dating back to the late 1800s. A working record player with records, table and chairs, bathroom, several lightening options for the overnight stay and personal lighting. The check in time is normally with the last tour of the day (4 pm) and check out is shortly after the first tour begins (10 am). Guests can check in earlier and stay later… but the caverns have guided tours 363 days a year along the concrete trails that curves around all sides of the room, so privacy is limited during tour hours.
