I have stayed at Wilderness Lodge, Animal Kingdom Lodge, Saratoga Springs, and Beach Club.
-Out of those 4 the best choice for teens in my opinion is Beach CLub, because
it has a great pool area for all ages that is great for hangout, and is a walk to the world showcase which is a fun place for teens.
I've stayed at Port Orleans Riverside twice (going on three soon ).
There are so many pools, and the surroundings are beautiful. I find it very relaxing and pretty.
