For spending time at the resort, I would recommend Animal Kingdom Lodge.
I would recommend looking into more park days though, possibly with a stay at one of the monorail resorts. We love staying at the contemporary and being able to walk back and forth to MK. We will often do a park in the morning, head back to the resort, out to dinner, and then back over to MK to do a couple rides or fireworks, then not have to worry about getting tired kids and strollers back onto a bus. GF has a walking path now too, which is nice when the park closes and monorails are busy.
It really gives opportunity to do more of what Disney has to offer at a slower pace.
