My CM friend got to ride Flight of Passage yesterday as part of her training for the ride. She said it was amazing. Apparently waist size may prohibit some riders (one CM did not fit and is on a mandatory diet). And she said if you are over 6'4" it might be uncomfortable. There will be a sample outside the ride entrance to try first.
She says there's almost zero signage, only totem posts for bathrooms and small wait time signs. Nothing that makes it obvious where queue entrances are.
And she saw the bioluminescence for the first time and gushed about how pretty it is.
It's surprising that they've decided to take such a minimal approach to signage. When DAK first opened there was also very little signage, with the thought that it would force guests to explore off the beaten path. Instead, guests got frustrated that they couldn't find what they were looking for, and the park now has more wayfinding signage than any other (including lots of signs pointing to individual attractions, when one for the general land would probably be good enough). It sounds like this is an intentional design "feature", rather that simply not yet being installed
