Welcome to the Disney Parks Moms Panel, Kathy!
Currently, Advanced Dining Reservations for the
Tomorrowland Terrace Fireworks Dessert Party are not available after July 4, 2015. However, I would expect those dates to open up at any time.
A hint to help you book these coveted reservations: Reservations for this dessert party have been known to open at any time during the day. Therefore, even if reservations for the day you are looking for don't open at 6:00 a.m. online or 7:00 a.m. via telephone, keep checking throughout the day. Reservations for my most recent trip to the dessert party opened at 10:30 a.m.
I hope this helps with your planning. If you have any more questions about the dessert party or any other aspect of your Walt Disney World vacation please come back and see me.
Wishing you a
*MAGICAL* vacation and a pixie-dusted day!
