Ive done Darkness and Creepy World all in one night. I would say be at Creepy World first when it first opens. Go to Lemp get speed pass for it and Darkness and you should be able to do them all. Lemp is close to the Darkness. Creepy World is the busiest in October. Make sure you go on a weekend when they are open till 1am. If you were to go in September you could maybe do it because they wont be as busy and there would be less of a wait. But then they may not be open as late either. Go to www.scarefest.com for times.
