Our group did the over night tour it's 100.00 plus tax. Well worth it!
The 4 hour tour was like 30 and was fantastic. Really see all the buildings and floors.
There are different price ranges depending on the tour itself. From 15 to 100 per person. The one my husband and I went on was vip tour for 35 a piece and the criminally insane tour was 15 a piece. I think their website lists the tours and pricing. There were 15 in our group. We did not get a discount.
