I wonder if a concept like this would have a casino. A ship would be a great location for more escape rooms, too.
Because of the more adult target crowd, the themed bar experiences would probably be truly phenomenal -- one could do Dom's Garage, an Amity Pool Deck bar, something like the Burning Blade, an in-theme Jurassic Park bar with break-out "moments". This could let them dip into some of their less park-friendly brands like Mamma Mia! or even The Notebook. Shows could include Back to the Future, Wicked, and Pitch Perfect, for sure, or something like Sing!, or even something like an E.T. musical. Definitely a Dreamworks area for kids...
