A huge media event again was in the planning originally before the corona delay. Now I honestly wouldn't hold it against them to just say "hey it opens tomorrow have fun" suddenly to prevent a rush of fans trying to book tickets to visit that day and deal with swarms of people. You'd think a majority have lives and can't drop everything to rush to PHL for the first day(s) so crowds would be more spread out.
People who'd need to travel from a far or internationally for instance too.
Of course that theory may be totally wrong and I've misjudged the dedication of some fans out there.
However the only thing that makes me think there must be some kind of considerable notice is that you'd think they want to start taking hotel bookings soon? With the hotel seemingly finished as that staff preview event includes a chance to view it and the park has been hiring staff. Unless with the situation they have decided to phase open them. F.L.Y. opens this September and maybe the hotel weeks later or the following month. Given covid I feel anything is possible now.
If it's part of the queue as predicted, I wonder how they're going to cover the wall beyond the top of the facade while you're in the queue. At the minute it looks like the fake bricks don't go very high, or I could be totally misjudging the height of the path relative to the top of the bricks!
The section of queue that goes behind there is in an enclosed tunnel. You won't be seeing it up above.
