Our building is unique in the fact we have an add-on. The original portion of the building has a drop ceiling at the height of about 10'. Panels are the standard 8' with a 2ft addition added to the tops of panels when and where needed. On the other hand, the new portion of the building that was built does NOT have the drop ceiling so it's somewhere near 20'. Every year I switch up the theme and typically I tailor the front part of the haunt (10') to ideas that naturally have lower ceilings and the same for the back half (20'). Ex. being two years ago when we did a factory theme, the front portion was mostly offices and such but the taller sections were boiler rooms, sections with bridged areas that could utilize the higher ceiling and we even have a "second level" that guests don't have access to but an actor can stand up there and interact from a height. We've dropped barrels from heights and even have had actor ziplines. Having both ceiling heights has been a fortuitous accident!
