It seems that advance booking was only offered during the "trial period", which ends 12/31/02. After this date, the "old" booking policy of up to 7 days out, in person, applies. Certainly, anything can change. Here is some more info for you:
I was told this week by WDW-DINE that the current Priority Seating trial will be available until Jan. 31.2003 and after that they may add, on a month by month basis. So, I was not able to book for Feb. but to call back and keep trying---on my dime!
I didn't know you could book the Fantasmic Dinner Package through the Disney Club. Would you give me the telephone number you used? I am a DC member! Thanks for the info.
