My favorite room was my last room (s) 4479 and 4481 at AKL comprising a two bedroom suite. We had a great view of Uzima savannah out one balcony, and the double wide balcony was overlooking the edge of the hot tub area/savannah. What I liked about that view was hearing the lovely African music drifting up as I watched the bongo line up to eat.
Another favorite is room 726? (I think), at the Swan. We always say hi to our room as it is easy to spot. It is the top balcony on the corner facing the boardwalk. Good view of illuminations plus where else can you dance on the boardwalk bridge and sing to your kids who are waiting for you on the balcony? (a moment they'd like to forget!) It was a wonderful room where you can lay in your heavenly bed and look out upon Spaceship Earth, or look forward and see a great view of the Dolphin out of your other window.
AHHH can't forget 4466, a reg savannah view room. (Yes you can request a different room than deluxe if you're staying concierge!) When you look out all you can see is "MY SAVANNAH!". I've also been next door during a trip in 4465, but 66 is on the corner and not only has a slightly longer balcony, but has an extra chest of drawers in it and a bonus long hallway/entry way as part of the room.
They're all favorites in one way or another (even that first allstars stay!; They're all Disney!
