My experience with waits last night:
Hill House (5:40): Stay & Scream was posted 20, actually 5 once the house opened
Puppet Theatre (6:00): Posted 5, Actually 3
Wicked Growth (6:10): Posted 25, Actually 15
Scarey (6:45): Posted 10, Actually 7
Texas Chainsaw (7:35): Posted 55, Actually 50
Case Files (10:00): Posted 50, Actually 25
Tooth Fairy (10:45): Posted 55, Actually 15
Bride of Frankenstein (11:20): Posted 35, Actually 25
Icons (12:10): Posted 65, Actually 20
I got in line for Beetlejuice around 12:45 when it was posted 85 but bailed after ten minutes because I was tired and the actual wait looked close to the estimate. I'm opting for Sunday or Thursday the next time I go; once crowds picked up, they didn't die down. I'm glad the waits later in the night turned out to be overinflated aside from Beetlejuice.
