This is a totally off the wall, fresh in my head, and probably bad idea. It’s also a potentially good idea for a movie theatre.
Pair a kid movie and an grown up* movie and package it with popcorn and sodas and call it the Date Night Package.
Have supervision for the kids and let the parents have a couple of hours to themselves while they watch a film. It saves on baby sitter fees. It gives the theatre more revenue. Add in pizza in the birthday party room beforehand and you have a complete date night.
*This originally said “adult film” but as the commenter pointed out, that could be misconstrued….or not whichever the case may be.
