Another Kent Gardens parent here with DS in French LI. They do an excellent job of combining both LI and AAP, which I think is even more impressive than going to a AAP center school. We were offered to transfer to a Center and declined. Even if my DS didn't get into AAP, or I had to choose between LI and AAP, I still value LI much more as language skills are better developed in younger years and you can always enrich via Kumon, Mathnasium, etc.
