Was at the park this morning, and alas, they were back to their usual hiding spots.
But I will say that I believe this attraction deserves a bit more credit in terms of crowd popularity than it gets. It had a 30 minute wait at opening (11am), and it generally seems to hover about 20 minutes throughout the day... and that's something that was designed to be a people eater, so really, waits should be 5-10 all day.
Plus, shortly after the initial opening, it had fairly limited hours... it'd be open for 90 minutes (or less!), then closed for 30, repeat... and then frequently closed one to two hours before the park did, even in the off season. It'd be closed by 5 if the park closed at 6. This went on for months.
Now, while it does have a delayed opening, generally seems to remain open all day without any closures at all, and during the off season, when the park closes at 7pm, stays open right until park close. So clearly there must be enough demand to keep it open.
If the park remains open until 10pm, it does still close a few hours before... but that's acceptable to me, as basically the entire park is generally a ghost town after 8pm, with even FJ being a walk on.
