We are just about finished with our guest list and are about to order invitations. We are really torn about how many to order, since a lot of our cousins/siblings are collage age. For the most part, they have their own apartments at school, but they still live with their parents over breaks. Do you think that it's ok for us to just include them on the invitations that we send to our aunts and uncles? A few are engaged, or soon to be engaged - would it be ok to lump their significant other in?
If it makes any difference, we plan for the invitations to arrive around Thanksgiving.
