Set up MyDisneyExperience first and get your room reservation, guest list, and credit card into it that you will need to preserve the restaurant reservations. Then make restaurant reservations on-line at Disney Dining. You should be able to make them for arrival date plus 10 beginning about 8 a.m. eastern at exactly 180 days out (possibly you can reserve before 8 a.m. but I have just not tried earlier than that). Nevertheless sometimes the system is screwy and won't let you reserve beyond 180 days out. Also, because of all the steps you need to go through on-line for each reservation, you might want to consider just calling MS at 9 eastern and make the reservations. I have found the time it takes to do it on-line when you have to do multiple reservations is usually about 10 times longer than it takes to just call and do them (have you ever been asked on the phone after making each reservation to sign off on a three page legal disclaimer?). It is Disney's way of showing us how much computers have improved our lives.
