Hi Stefani! You will be able to make advanced reservations 180 days out, which I believe is March 25th for you! The number to call is 407-WDW-DINE.
And I also have good news for you that the dates for Mickey's Not So Scary Halloween Party were just released this week: September 5, 9, 12, 16, 19, 23, 26, 28, 30 and October 2, 3, 5, 7, 9, 10, 13, 16, 19, 21, 23, 24, 26, 28, 30, 31. The tickets will go on sale on May 1st, but the prices are not available yet.
I'm so happy to hear your thoughts about the panel. We are all enjoying helping others plan for trips to WDW!
