I meant, like, on a day they decide to do a soft opening, how long do they usually let people into the ride before they close it down again? Or is it open all day during a soft opening day?
As I said, its unpredictable. It can be for most of the day, or only for the last two-one hours of the park hours. It will really all depend on if theres a few factors into the mix, like plenty of TM's in full costume coming in; or (for when USH did it), having a line set-up to go into the area to ride it (USH did this for Hogsmeade, and it turned out very interestingly).
