I had to call a couple of days ago to make my reservations. I called Disney Dining. I was worried because I have a split stay and didn't know if they would let me make the reservations for the entire stay, or just the first part. I was able to make ADRs for the entire stay (past the check-out date of the first resort).
I had to call this morning as well. I got through with no wait at all and got everything we wanted within 10 minutes at prime dinner time (CRT dinner, CP pre-opening breakfast, 'Ohana dinner, and more popular restaurants).
When this thread was current, yes it was solved. Since they released the new website, there have been some additional problems that they are working on.
Just asking... Overall I have never had a problem trying to get dinner reservations, and I didn't have to get up at 5 AM to try to log-on 180 days out. (Not that I wouldn't).
For those of you that do is because of large parties, or one specific day during your stay? I realize some of the dinner shows may be more what you are trying to book. Just curious..
