Some have had problems trying to book online. There are some CM's that seem to be misinformed that the DP is now available for reservations. I'd call back. Now, there may be a possiblility that there are some dates that are filled up. As far as a phone number, call Disney Dining: 1-407-939-3463 Booking for April just opened up today. For the past few months, they have been allowing for booking about 30 days out. The party begins about 1 hour before wishes (despite what the reservation is), and ends after the fireworks end.
