My fiance and I chose a mid week wedding Aug 17, because all of his family has to travel. So we did our research and flights are cheaper mid week. This would let them Fly in on Tuesday and out on Thursday and miss the weekend price bump. Also we got a great deal on our venue because it would have been empty otherwise.
I've been designing my save the dates and my maid of honor asked what the date was. I told her Aug 17, 2016. She responds back say that she doesn't think that will work for her because her husband works (apparently I don't?) and she MAY be taking summer classes.
Am I really supposed to change my date for her? Or should she be more flexible? Since she's my older sister can i play the "its my wedding and I can date it like I want to" card?
