Good observation about the environmental storytelling.
If you are happy with the layout and willing to go all out on polish, first idea that comes to mind is to go for a “villa has been recently restored, owners/organisation is organising the inauguration party and Ts want to blow it up”, so it’s a good occasion to have some back rooms half painted, full of tools etc, and open areas very clean, some bunting/flags, a stage and loud speakers… that sort of thing ?
