Other poster is right. You can only make res 90 days out. In the meantime, call 407-WDW-DINE and find out exactly what day is 90 days out
This breakfast is one of the hardest reservations to get, so try to coordinate with several friends/relatives and get them to call exactly 90 days out too.
There is a huge thread on suggestions at the top of the restaurants page...
