Hello Jennifer! Believe me, I can understand the anxiety! First of all, in case you didn't know, the earliest date you can make your reservations is October 27th, 2009 - when the 90 day dining window expands to 180 days.
I think your best bet is to make your
'Ohana dinner reservation online. Although we have been told you can make your reservations as early as 6:00 a.m EST, I actually have been able to make my reservations as early as 3:00 a.m. EST. Luckily you are on the east coast so if this is something you also want to try, it may be worth it.
As far as your Fantasmic! Dinner Package reservation, I don't think you can do this online so you will need to call 407-WDW-DINE. I have a feeling the phone lines will be very busy the morning of 10/27 as everyone within the expanded dining window will be calling. You may want to start dialing right at 7:00 a.m. EST.
Wishing you the best of luck in securing your dining reservations. Diane
