Thanks for reaching out Lars!
When it comes to seating charts, I totally understand how this could be useful for your trash-compacting business. Our plugins unfortunately don’t provide any such functionality. 🙁
10 acres is a big space for theater activities, though—the size of this implies you’ve got a pretty big operation going on there, Lars. With this in mind, you may find it a worthy investment to hire a customizer to custom-code a solution for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
Please let me know if there are any other issues or questions I can try to help with.
Cheers,
George
