If it weren't for AKV we would still be sitting on the fence where DVC is concerned. We had looked into it for years, starting in the late 90's but none of the current offerings really blew us away. We liked the other DVC resorts its just that we were looking for that something extra to make us pull the trigger. It was the announcement of AKV that made us do that.
My sister and her family had stayed at AKL a few times in the past and we were always jealous of that, doing most of our stays at Port Orleans or similar. We had our first DVC stay this past August at AKV in a 1BR SV and it was fantastic.
We really like the remoteness, something which many complain is a disadvantage. In my opinion, that's one of the very things that makes AKL/AKV special. It helps add to the illusion that you are on some African safari far from civilization.
We particularly loved the fact that AKL/AKV has their own bus route, separate from all the others. We never waited more than 15 minutes for a bus regardless of time of day and there were several occasions where we were the only family on the bus. In comparison, we stayed a couple weekend nights at one of the value resorts to save points and there were several times where we had to wait for a 2nd or 3rd bus just to get a seat. I'll never go back
The fact that they are the only DVC resort with concierge level units (along with the value unit point costs) was icing on the cake.
I think AKV will only improve and become more popular as the Kidani additions are completed, they continue to add new attractions to Animal Kingdom and the proposed expansion plans on that side of WDW become reality.
We love the whole idea of DVC and all the resorts, but its AKV that really makes us feel like its something special.
