Wedding Jackson Square

I'm getting married in an informal outdoor wedding in Jackson Square and our guest list is already 35!

That is one minute 6.10 to exchange vows while standing that, very informally, and then out for a reception. Is this possible or am invited to some people their wish and everyone at the reception?

I would say to go ahead and invite them and let them decide whether to go or not. As stand no need to prepare the chairs, etc. ..
