We were not going to register because we wanted people to come to the wedding rather than buy gifts. But, there are people that you do not know well enough for them to attend, and they will want to buy you gifts. Plus all your extended family that may not be able to attend will want to come to showers and AHR. We registered for those people. Although, we did not tell people we were registered. We only told our parents and wedding party, just in case anyone asked them.
