We have about the same plan as you. Our package is for the 6:45 show and dinner at Le Cellier at 8:30!! This will be our first time at WDW. Can't wait to see everything and spend Chrsitmas there.

Have a great time!!
PS If you see a family of 10, with a toddler and 12 year included that's us. Hopefully, we will all be behaving!
