I have DS12 and DD11. We called long, long after we made our reservations and had our room preferences added to our reservation only 2 weeks before our trip. We asked for Springs, then Congress Park, then Grandstand. We were given Congress Park - with great views of Fulton's and Cirque du Soleil. We walked to the main pool once and were not overly impressed with it. It wasn't crowded but nearly every chair was being reserved by a book or a pair of flip-flops. Once you use the slide at SAB, everything else seems to pale in comparison. For future swims we stayed near our room and used the "leisure pool" there. The kids loved having a pool (and hot tub) to themselves many times. It was a bit of a haul taking my 4 refillable mugs all the way down to Artist's Palette and back every morning but that is my only complaint related to location.
Our location in Congress Park made for a very pleasant walk to DTD most evenings, although it was a tiny bit secluded on the path. The thought ran through my mind that a person could get mugged and their body thrown in the water and no one would know, but then, I look for things to worry about. Fortunately, MousePolice on bicycles patrol that path.
Regarding wildlife, we saw dozens of the most beautiful brown bunnies hopping around as well as mallard couples. We called them "Disney bunnies" because they were the healthiest looking wild rabbits I ever saw. I don't recall anything more exotic than that, but we still enjoyed seeing them.
