Can I Please Have Some Help With My Small Business? Ideas Needed!?

I run a small indoor pirate themed children’s soft play and i have been offered to have the building next to mine. I want to expand my business bu i was looking for some ideas of what to use it for. its 6000 square metres and i would like to keep the pirate theme. At the moment, ideas to exclude because i have already thought of them are: laser emporium, bar, skittles, Roller skating rink. I need some new ideas!
thank you
