I'm getting married in 2.5 months and have 5 attendants - 3 friends and 2 future sisters in law. I JUST found out that one SIL, who lives a 5 hour drive/2 hr plane flight away, has an important college exam she has to take the morning of the wedding - it starts 7.5 hours before the wedding starts and apparently cannot be rescheduled. She told me she will figure out a flight and be there in time. I say it's insane to ask her to start, finish, get to the airport, fly, arrive to the wedding in 7.5 hours and we should just say it's not going to work, and get a different bridesmaid. Maybe we could have her read a poem if she gets there in time, and obviously she can come as a guest - but I don't want the stress of a bridesmaid in a different city the morning of my wedding, on top of everything else I have to deal with on my wedding day. No hard feelings, it's just not going to work. My fiance says I can't ask her not to be a part of it now, I have to just hope the flight doesn't get delayed or that she doesn't miss it because the exam takes longer than she thought.
