I like all 3 resorts, for different reasons. But my top pick is definitely AKL, Jambo House. If you book a standard-view room, request a partial savanna view--those rooms have really wonderful savanna views, and sitting on the room balcony and watching animals is one of my favorite AKL things to do. Or you could pay just a little bit more for a pool-view room, and those rooms are pretty wonderful too, and from some of them you can see animals.
If you like art, AKL has one of the largest collections of African art outside of Africa. It's in all the hallways. You could literally spend hours just walking up and down the hallways in the building, looking at all the amazing artwork.
Another great advantage (to me) of AKL is its proximity to DAK, which is my favorite park, and the buses to and from DAK from AKL run very frequently. You didn't say if you're getting park-hoppers, but if you have them, you might enjoy, as we do, ending the day with an evening at DAK. It's beautiful there at night.
That being said, GDT is lovely and if you luck out, you could get a room (water view side of the resort) high up enough that you can see the MK fireworks from there.
We also like POFQ. As a PP mentioned, the boat to DS is great, the grounds are beautiful, the rooms are nice, and the food court is pretty good. Also, beignets. In the morning, POFQ doesn't share a bus with POR until after 11 a.m. (at least it was that way last month) and on the way back from a park, it doesn't matter, since POFQ is the first stop.
You have only 4 park days, right? Study up on
Genie+ and ILL$. You'll want to maximize your use of them to do your most-desired attractions. Rise of the Resistance at Hollywood Studios, even if you don't care a twig about Star Wars, is just amazing. Well worth the extra $ for the ILL$, if you can swing it, since the queue there is often hours long. Ditto Flight of Passage at DAK.
Have fun! You will, no matter where you stay.
