There are 4 Stay and Scream areas. Hollywood, New York, Diagon and Simpsons
I used all 4 S&S last year and Diagon was by far the best, least crowed and spread out. New York is stupid crowded. Hollywood is fair to crowded depending on the night and Simpsons is really busy for RSVP (16th, 17th 23rd and 24th) but dies out a bit when those nights are done with.
