But at this point, the theme of the MCU seems to be the Multiverse. So any E-Ticket really should be a trip through the Multiverse - maybe helping Loki restore the timeline or having The Watcher send you off on a mission. It would be all thrills and screenz so I couldn't go on it, but it would be nice to have a counterpoint to Star Tours at DL where you can go to different locations in the MCU/Multiverse (though that could also be done with Doctor Strange/America Chavez portals). I guess Mission: BREAKOUT has multiple choice experiences though and probably counts, too.
