I wouldn't be shocked, but at the same time, the week of Christmas and NYE is the one week I feel confident still in saying DL will be slammed. So why soft open a ride during an extremely busy and stressful time when you could soft open it the week following NYE as a way to bring locals out to the park during a typically quiet time of year?
I mean, most APs are blocked out during that time and nobody's booking a last minute flight because they heard the ride soft opened. I don't see how it really actually CAN affect crowds that much.
