When my kids were 2 1/2 and 3 1/2 we couldn't get my son (3 1/2) past the turnstyle. Just the building and the CMs spooked him. At "just" 5, we got him in, the holding room spooked him, he almost bailed, but made it through. Both he and my daughter ("just" 4) throught the graveyard spooky. At 6 and 7 they both still cover their eyes through the graveyard.
