Technically they are open almost to 9 every night with the Echo Hollow Show...
Duelist,, hate to disagree with you... But Echo Hollow starts at park closing usually 6, a few times 7., Only time park is open any later is Moonlight Madness, and OTC of course. and the 3 Midnight days this year....
Echo Hollow show last 90 minutes, When we leave at that time of day, You see Nobody on the way up the hill. The park (food, rides,shows) all end at 6:00, that is closing time..
