We've stayed at AoA three times so far and have another stay coming up later this month. The suites work really well for our family (we have 5 teen/adult children but only 3 or 4 of them stay in the suite with us). We eat breakfast in the room almost every day so the kitchenette is very handy for us. I love having a master bedroom and bathroom. We really enjoy the pools and the food court as well. Our "kids" don't like to share a bed with anyone so we take an air mattress or 2 along (we drive to Disney) and there's plenty of space to use them. We've stayed in both the Nemo and Lion King suites and like the decor and location of both of those sections. They both have many rooms that are just steps away from the food court (important to us because we use the refillable mugs a lot) and the bus stops. The Cars area is absolutely gorgeous, especially at night! The room decor doesn't appeal to us, so we've never stayed in one of those suites.
I think the only downside for us (as Coaster Lover also mentioned) is that AoA is usually one of furthest (if not *the* furthest) bus stops at every park and at Disney Springs. It doesn't stop us from staying there, but it is annoying. The first time we stayed at AoA (about 9 months after it opened) the bus stops at the parks were much closer and at one park (don't remember which one) it was the closest stop. When we went back a year later they had changed the location of the AoA stop at every park.
