I assume the poster is referring to individual buildings being spread out with outdoor paths connecting them, similar to a college campus. The lobby building is sort of like a student union. Not always fun in the rain, but the style does invite a feeling of exploration and adventure which fit the original Poly nicely IMHO.
The trend toward taller self-contained buildings provides those who can't or don't want to walk long distances more convenience but does tend to lose a lot of charm.
Animal Kingdom Lodge (at least Jambo House) I feel threads the needle nicely in this regard. An expansive and richly detailed lobby full of paths to explore and secrets to discover, with sometimes long but fully enclosed hallways to the individual rooms. Those long hallways are broken up by design with large windows providing ample sunlight and unique views to the savannah. A good choice in the summer to be sure.
Port Orleans is another great example of campus-style resort layout which, while mostly outdoors, excels due to its location and charm. Not perfect in hot or rainy weather but outstanding in the cooler months.
Given a choice, our family has usually trended toward the "campus" style resorts as having a connection to the outdoors is important to us. But tastes definitely vary.
