and please don't bash me, I'm honestly not sure what's appropriate. We are having a small wedding, 46 guests. Do I need to add a plus one for my family guests that I know will not be bringing any one? Should I put one just in case? For example: I'm 110% sure my Grandma will not be bringing any one, but my Aunt for example, I'm pretty sure wouldn't. She is not seeing any one. Is she "allowed" to bring a friend?
