You can make your own ADR's. I tried at the 90 day mark and couldn't get the online ADR system to work for me. I ended up calling Disney Dining at 7am eastern time and got all of our ADR's within 15 minutes of the time we wanted. If your going to use the dining plan the person whom your renting from has to call MS and add it. Have alternate times and places you can live with ready just in case.
