I called yesterday because I was told by someone at Disney Dining to call on that day. When I called they said I wasn't eligible because I was calling too early! They told me to call today. I'm arriving on the 27th of May. After trying 4 different times w/ my longest wait of 20 minutes I finally got to make my reservations! Also if you are staying on property be sure to have your reservation #. They had to look mine up to make the reservation. They also said something about changing their reservation system this week.
