Sorry for your loss. I cannot even imagine what your family is going through.
As for your trip...we took our son for 10nts when he was 8, 2 years ago. He loved:
Water Parks
Disney Quest
A few character meals...especially Restrauntasaurus in AK. Yeah Donald!!

Also big hits with him were O'Hana at the Polynesian and Whispering Canyon Cafe at the Wildernes Lodge. Lots of fun for kids their age!!
He loved getting autographs and pics with as many characters as possible.
Rode in the front of the monorail with the driver and they gave him a Co-Pilot license!! It's in his scrapbook.
We let him take his own digital camera and he got some AMAZING pics!! Great to see a child's perspective on a holiday!!!
Fort Wilderness for Horseback riding in the morning, campfire sing-a-long at night with Chip and Dale, followed by a Disney movie under the stars!!! Another big hit!!
Checking out the Animal Kingdom Lodge at dusk. Animals are active then, CMs will tell you all about them and then there is a story time by the fire-pit later on. We had to miss this though.
Mini-Golfing at WinterSummerland!!!
Taking a LOT of time at the resort to swim and rest!! Late, LATE night swimming was also a big hit!!!
You guys will have a blast!!! Enjoy!!!
