We just got back. We stayed concierge, too, but our room was on the 5th floor - 6th floor is the dedicated concierge floor, and also where the Kilamanjaro Club (the lounge) is located.
We were on the Kudu trail, so we had great views of the savannah and Arusha rock. It was something of a hike to the elevators to get to the Kilamanjaro Club, but no big deal.
This was our first ever concierge stay anywhere, and the pampering level was outstanding. BUT - if I had to choose between concierge and a pool view, or non-concierge and a savanna view, then I'd go for the non-concierge in a heartbeat. The view from your balcony is what makes the AKL, IMO.
I guess it depends on what "extras" you'd expect from staying concierge, compared to the extra outlay of $$ (and if that's not an issue, then don't fret.) We stayed on DVC points. For the extra points/$$, we got all the food goodies at the concierge lounge - we managed breakfast there nicely, and one evening indulged in the heavy "snacks." We had turndown service, altho I think that can be requested no matter where your room is. And, we didn't use concierge for pre-trip planning like we could've, but that might be a plus for you.
Misty, there's some great photos around here somewhere. Personally, if I were gonna spend more time at the resort as opposed to the parks, concierge is great, but if you're mostly gonna use your room for sleeping, then I'm not sure if I'd think the extra outlay would be worth it.
I know I sound ambivilent. It's because I am.
