I think it's a good choice for your group. We have stayed there with others and multi generation, and it is a resort I suggest to family/friends who have never been (and so far they all loved it).
Relaxed southern charm theme, good theme pool that kids will like at all ages because it has the "kid section" and "older section" as we call it, great quiet pools, boat to DTD which is good for all or even your older kids if they want to go to DisneyQuest on their own, sit down, fast food, bar that everyone enjoys, fairly centrally located in the world, water amenities, share with POFQ, two distinct themes and nice to walk around......I think you'll enjoy it.
I do suggest you book some dinners at other resorts to check them out....BOMA at AKL and you can take in all the animals.......great way to see the world. Have a wonderful wonderful trip !!! - OH how I wish my ILs had wanted to do that for the 50th, instead of a labor intensive party....
