There are a ton of threads talking about this same problem. I too am trying to book a F package and SoA for our May trip and I haven't had any such luck. Try calling everyday, because according to the CM that I talked to this morning the F packages should be plugged into the computer within the next couple of days (now not sure if this person was just blowing smoke or actually new the ETA). As for SoA, book it online at exactly the 180 days from the date you want to dine there. I did a mock ADR to see if it will show up and sure enough it did. So now I am going to have to wait until Friday to book that dinner show. Good luck to everyone.
We had no problem booking SoA on Nov 7 for our May trip by phone (within our 180+10). You may want to call back and try a different CM. Are you on the dining plan? If so that may be the problem. It seems that people are having problems booking certain things that haven't been loaded with the dining plan. Some CMs seem to realize this (apparently they have to uncheck dining plan to make a reservation otherwise the system doesn't search for it) others just think it isn't loaded. You could probably make the reservation as if you were not on the plan and later update it to use the plan for it. Fantasmic though really doesn't seem to be loaded yet for anyone.
To the pp - you got through today? I have been trying all day to book my f! package and the system is all down. How did you do it?
