We've stayed concierge level at AKL twice, and my, what a treat. The first time we stayed was through the
DVC Disney Hotels Collection. We transferred out- $95 fee- and stayed concierge at AKL because AKL was not part of DVC at that time. We had a great two queen bed room on the 5th floor overlooking the main Arusha Savannah. The staff was great- they got us wonderful seats for La Nouba, signed us up for the Sunrise Safari (which is so worth it, by the way), and had all of our ressies were made exactly as requested. The savannah view was incredible- we had an excellent vantage point. The food in the lounge was superb and very few people were in the lounge during prime "eating" hours.
A few years pass and we returned last January to stay again through points- without the $95 transfer out fee. We booked a one-bedroom on the sixth floor (all DVC concierge rooms are on the sixth floor now) and requested a savannah view (which was granted- keep in mind that only half of the concierge rooms for DVC are savannah views vs. non-DVC concierge rooms, which are all savannah views). Our request was fortunately granted and the view wasn't as bad as I expected. The view is of a smaller savannah. One thing that I definitely noticed was that the noise of the lobby (the music played on speakers), children screaming/yelling, adults talking, and general movement comes in faintly through the main door, so it wasn't as sound proof as other rooms in the resort. I liked how we were so close to the lounge (also on the sixth floor). The food has definitely declined in amount and decreased a bit in quality, but it's still good and a great deal. There are a lot of great offerings at this lounge that make it unique (especially the African wines) in comparison to other concierge lounges at Disney. The lounge also seemed a bit more packed in the past even though we were traveling in mid-Jan- an off-peak time. Would I say that it's worth it paying cash? Absolutely not. On the other hand, when staying on points (especially ones that will expire and can't be banked), this is an awesome choice and way to use points. We loved the daily housekeeping AND turn-down service. The concierge staff still do a great job in making all reservations. Staying concierge made us definitely want to reserve a day or two to just take in the resort and everything that it has to offer.
Good luck reserving! As previous posters have mentioned, it's really hard to book at 7 months, but it can be done- usually during off-peak times, but you'd be surprised. It's worth a shot, but also have other resorts in mind in case you have to waitlist and the waitlist doesn't come through. PM me if you have any questions.
