The Cabin in the Woods is real
At least, it will be. Once Universal Orlando is done building it.
Universal Orlando has announced that it is recreating the infamous Cabin as a maze attraction in time for Halloween.
Talking to Zap2it, Universal Orlando's Michael Aiello explains that the amusement park is building the cabin for Halloween Horror Nights 23:
We are building the cabin completely. You're going to walk through a forest to get there. You're going into the cabin. You're going to go into the cube cells. We're literally taking everything we can in the film and giving you a kind of best-of montage of the film with this kind of linking story. You're going to be in the control room when merman attacks.
