I would be sure to request savannah view if that is what you want ...the concierge rooms at AKL (unlike the other rooms) do not have guarenteed views. The rooms are either on the 5th or 6th floors...we have been on 6th floor both times which is great because it is so convienent to the lounge, however the balconies on 6 are all partially obstructed by the roof lines....so if you want a bigger balcony and better savannah view (but a longer hike to the lounge) ask for 5th floor.
IMHO it is the finest concierge service on WDW property. (and we have stayed at all of them except BWI)
If you like the AKL you will LOVE the concierge floor there!!
