I love this idea, but...I'd love it more if it weren't presented as an "elevator to space" but rather as a rocket-ship launch to the space-station restaurant. As I walk into the place, I don't see a big tube going into space, so the story is broken if, upon entry, there's an implication that there's some elevator shaft. I'm sorta thinking of something like the pods that ascend/descend from the Zephyr on Agents of Shield.That other site is reporting what we have been speculating for quite some time. The new Space restaurant will use "transportation chambers", similar to the Sea's long-gone Hydrolators, to get guests "up in to space". This effect is something I'm personally very excited to experience.
So I guess, imagine a vestibule somewhat similar to this but with an acceding into space effect vs the descending under water effect.
I'd also like ride such a pod as I exit the restaurant. If done well, the entrance/exit from the restaurant could be an attraction of its own.
