Just my opinion about having weddings in cemeteries.
If the cemetery itself allows you to have your wedding there, then that fine.
My mother's family has a small cemetery on private land with graves dating back to the 1840s.
It is on private land, in a rather secluded place, with appropriate signs, security, and is obviously not open to the public in any way for any reason.
You would not believe how many people have attempted to use it for various events like, music videos, film projects & raves. One stunt even had people DIGGING (there are unmarked graves there as well.) on the property & attempting to rearrange headstones.
Even the shiny new padlocks, gates and freshly mowed grass didn't clue folks in that it was not abandoned property.
Family members have now had to remove the original fencing and put in extreme security measures.
So I'm sorry but even I hear of people having wedding in a cemetery environment, my first thought is: You did ask to use the venue, right?
