Another fun one is to take the boat from MK over to WIlderness lodge and go to whispering canyons. Rowdy fun, good food, and oh I just love that awesome lodge! (Kids liked the boat ride too!)
I agree about Chef Mickey's -- we really enjoyed it -- a must-do for us to get in the mood! Monorail to Contemporary (which kids think is way cool, too).
I have heard mixed reviews on Liberty Tree in MK -- some like it, some don't. I personally find it hard to eat Thanksgiving dinner in summer heat, so for me, it's more about the season than food or service! Just can't get in the mood for turkey at all times...
As for dinner after AK -- just remember that AK closes earlier than most parks (critters need their sleep too ...) So don't feel dinner has to be there, necessarily -- maybe a good time to try something fun like a Hoop Dee Doo revue, Mickey's BBQ, or (less involved) one of the many great resort restaurants...
