Not sure what the exact hours are, but I know TSI used to close at about dusk. I'm sure that is probably still the case. It's dark out there at night, and they need to use the island for F!.
The OP is going in 14 days, so I'm pretty sure F! will be running again then. And, even on the nights F! is not showing it seems to me that the island closes at dusk. As I pointed out before, it gets dark out there at night!
That makes sense...thanks! I was hoping that maybe after getting my Space Mt. FP that I'd head over and get my Splash...then stick around that area for rides and Pirate's Lair until it was time to ride Splash...just something to do while waiting and didn't know if it was open early...or "up and going" by then
