Animal Kingdom Lodge is open but since it's a 'secure' resort you won't be able to go look around unless you're having breakfast or dinner there *and* have a PS. When you call Disney to make your PS they'll require a credit card and will explain about the 24 hr cancellation policy and/or the $10 per person penalty. The 2 restaurants are called Boma and Jiko. Can't help with the type of food though, since I haven't seen a menu or read anything on the Restaurant Board.
DVCers won't be allowed to pool hop, although I think the possibility remains that once the 'newness' of the resort wears off that will change.
As for prices, there are quite a few deals (AP, upsells etc) for around $200/night for a savannah view room (check the resort board for more info). It's possible to use points to stay, but just as with the GF, Poly and Contemp, you get less bang for your point than if you were to stay at a
DVC resort.
About Stormalong Bay - if your 5 year old likes pool slides then he'll love SB. If not, then it's probably not worth the hike over to the Y/B Club from WLV. Maybe you could walk by (it's a short walk/boat ride from the International Gateway entrance in Epcot) and let him see for himself.
Good luck
