My daughter and her fiance both work for the same large market. A couple of people they work with have randonly given them gifts, but we have not invited them to the wedding. The reception venue has an occupancy limit and the invitations have gone out. Are we obligated to invite people who are randomly giving wedding gifts? I feel like we should invite them, but we are alomost out of invitations and the budget is already busted. Would it be rude to invite them to the ceremony and not the reception?
