Yes, for the most part. We welcome Do It Yourself decor (DYI) at wedding events with some limitations. We require that you tell is what you are bringing, who is setting it up, and who is taking it away/cleaning up. We may not approve all DYI. For instance.

Not OK (Partial list)
Arches, chairs, artificial flower petals, rice, your own recorded music.
