Just a quick review on our recent stay. We were at AOA in a LM room from 1/12-18. I requested a king bed and am so glad I did because our friend's room with two fulls was a little cramped, but we had plenty of room. I didn't request a building but we ended up in building 7 (Ursula) with a lake view and it was very quiet, except for the occasional luggage cart rolling by.
We tried out the LM and Cars pools and they were definitely not heated, though maybe because it was in the 80s while we were there?
As far as the thermostat, I didn't have a problem with it not going below 68 (we kept it at 70 most of the time), but the room did get warm overnight. I usually ended up getting out of bed at some point to wake up the thermostat and get the air moving again.
The walk to/from the buses/Animation Hall was a little long at times, but I think if we hadn't just run a marathon I wouldn't have minded it. There were a couple times where it felt like the buses for every other park were coming but ours, but overall I had no qualms with the transportation.
Overall we were pretty happy with it and felt it was a good value. I'd definitely consider staying there again!
