It would not surprise me, based on the fan-press coverage. Perhaps a better idea would have been a regular star cruiser hotel that is an open ended experience, where you come and go as you want. It could have been less specific two day event focused, and more like a place to walk around in and relax. They could have still had these interactive areas and stuff, but just let you (or your kids) do them whenever, and not center it around a story.
One perk could have been a second gate at Hollywood Studios for hotel use only, where attendees go through the exact same transport ship deal to get to Batuu. Then you might get people staying for longer and wanting it for that specific perk. The extra “on board” attractions would just be added on things for staying at that specific hotel, similar to what some of the little nightly themed events on campus already are.
I just keep thinking I’m probably a lot more likely to walk around the hotel atrium, bridge, etc and hangout than I am to actively participate in the planned events. Though I like stuff that includes gamification, I don’t want that where I eat and sleep. And as my girlfriend pointed out, we like to sleep in, and have downtime, but this experience would probably legitimately have us up 20 hours a day because we would be paying so much for it. I’m not going to sleep when that cost me about $800 in time.
