Ok, so I'm doing a very DIY backyard wedding. I have arranged for someone to come do hair and makeup at the location, but I have one bridesmaid who wants to go get her hair and makeup done on her own somewhere else. I'm not requiring them to do hair and makeup, so I'm not mad or anything, it just worked out the everyone wanted at least one service done with me. So what time do I tell her to be at the ceremony location? I don't want her to be bored and left out, but I'd like her there to interact/help some. My ceremony starts at 4pm.
