Hi, my parents said that they would throw my fiance and I an engagement party. However, I have an older sister (who I guess will be by default my Maid of Honor - I haven't asked yet). But she is out of the country/busy for the next weekends of about 5 months. I don't want to wait until September to have an engagement party (we want to get married in the Spring of 2014). Do I have to make sure she's free to attend?
