Disney opened an incredibly expensive Star Wars “hotel experience”, charging $5k plus for two nights. Jenny Nicholson visited (paying full price) and documented the experience, plus background on how and why the hotel was made, some research into what was going on behind-the-scenes, and the spectrum of fan reactions to the experience. The hotel closed down permanently while she was editing the video, and she also goes into why that happened and some larger trends at Disney surrounding the closure.
I don’t think Jenny is on Nebula. She’s got a patreon where she releases smaller videos every month, but to my knowledge she’s never “left” YouTube - she just takes a long time to create and edit these videos so she can only release them pretty infrequently. She’s got a comment pinned on this video saying about as much.
Are you thinking of Lindsay Ellis? She’s still Nebula (and maybe patreon) exclusive.
