Our wedding is in December, so we are sending our Save the Dates out soon. Our guest list is limited (100max) and my fiance wants to invite every single family member, majority are out of state, so I know they probably won't come, but if I invite them I have to "ideally" save a space for them until they rsvp. Is there a courteous way I can ask them if they are coming before I send a wedding invitation with an RSVP card. I know the etiquette but there is no room on our guest list for friends because his family is so huge, they take up over 50%! Ideas?
