Great PTR. Your girls are so cute, I love all the matching outfits. My adult girls still make fun of me for dressing them alike when they were little

, but I don't care. Looking at your pictures just affirms that it is so adorable.
You have some great plans for your dining choices. With such a long trip it will be nice for you to take the time to visit so many different restaurants.
I went with my daughter last year when she ran the WDW W&D 1/2 last year. We purchased tickets to the Epcot after party too. It was so much fun. We started early (I think they can enter the park as early as 7pm, back in the world showcase. Then as soon as the park closed to regular guests we went to soarin', and rode it multiple times with no wait! It was great, I think your girls would love that.
You mentioned going for a picture at Epcot with the Characters, not sure if the VISA site changed, but there is a closure report on another site that stated "The Character Spot located in Epcot's Future World closed on October 21 for refurbishment. It is scheduled to reopen February 2013. A temporary location will be available near the Fountain View Ice Cream shop where you'll be able to see Mickey, Minnie and Pluto. Also, Goofy is now appearing at Epcot's main entrance, near Spaceship Earth."
I will be arriving at WDW during your vacation, and am also hoping for warm sunny weather too.
Have fun.
