If you received a "save the date" card in January for a family member's wedding in early August, how long would you wait for an invitation? It's now two months before the wedding date and the location requires you to travel by car so you need to plan & budget for at least a 3-day trip. Would you contact someone to find out if you've been invited or not? Would you assume you're invited & decline other things for that weekend? What if it were six weeks away & you hadn't heard anything?
