We are having a Disney wedding, all of our wedding guests and party will be traveling from out of state to attend. Per the package we selected we are only allowed to have 20 people including ourselves. So that leaves 18 spots, we want to have two attendants each. The people we have choose to be in our parties are all single and not in a relationship of any kind. But who's not to say they won't be in a year....however, we need to leave space for family members. Would it be rude to simply ask them to accept not having a guest option? It is simply to open up four spaces for family members, not because we don't want to pay for their guests its simply a question of priority of those present for our small wedding.
If they would happen to become involved in a serious relationship over the next year (which happens as it did for us as well) we would obviously try to work something out. But we just don't feel it's nessacary to leave out family members for "maybe I will have someone to bring" guest for our wedding party members.
