We are eloping to Maui to get married by ourselves (but everyone knows about it). We were not planning on having any sort of reception, but my mom wants to throw us one. We have a few relatives out of state we would like to invite so that we do not hurt their feelings. We would be thrilled if they decided to come but we do not want to make them feel obligated to come. Is there a tactful way of wording the invitation so that we make them feel welcome but not obligated?
