My wedding is very small (30 total in attendance) and the wedding party only consists of the best man, maid of honor and my FH and I. We are not having a rehearsal dinner because there really is no need for a rehearsal. Still, we have several guests from out of town and want to spend some time with them while they are here that weekend. Is it etiquette to plan an outing somewhere but not "sponsor" everyone at that said event?
