How to write the notice of wedding parking space occupation?

I'm a wedding photographer! During the filming process, most parking spaces in the community were congested, and there were many wedding cars, so there was no way to enter the community. Most newlyweds will discuss with their neighbors to use their cars to occupy parking spaces one day or a few days before their wedding, and move them before the wedding day. Generally, it is just like writing a note, which has little effect.
