It didnt feel this long but I stood in a 3.5 hour queue for Flight of Passage at Animal Kingdom on my own. It was first thing so their wasn't any fastpasses cutting ahead and the queue moved quickly. Talked to people too which also made it feel quick.
Yall should watch. I think its my favourite film of the year surpassing Annihilation (which is on UK netflix so you should watch that too). All round a very strong film and doesn't rely on jump scares.
Even though it shares its similarities with Steampunk, i'd like to see Phantasialand try Cyberpunk (maybe in an indoor area), I think the compact/jam-packed style phantasialand do so well would work well for that particular theme.
