My favorite are the bathrooms at Animal Kingdom Lodge or Pop Century resort lobby area. Always clean, smell nice, no lines and soothing(AKL) or fun (pop) music playing.
Least favorite is by Refreshment Port, especially during F&W.
I do like AKLs. Those are nice.
I did like the bathrooms in my room at Animal Kingdom Lodge.
You must mean Jambo House.. the ones off the lobby at Kidani Village are single use ones.. so if a family is going.. you may end up being there a while waiting.. depending on where your room is.. you might be better off going back to you room if you have to go..
They are nice and spacious.. and always clean, but seems like every time I hit them, there is a line..
