We stayed at the AKL-Concierge this past April and I can't say enough good things about the cast members and the service. Due to the quirks of Grand Gatherings, our reservations were really messed up by the reservations system. AKL upgraded two of our rooms to concierge when I had only paid for one out of three rooms as concierge. The check-in process was extremely lengthy due to the problems and Kenny, our AKL concierge, was superb! I can't say enough nice things about the service. We had breakfast 3 out of 4 mornings and they had a great selection. My sister and her husband sampled the evening offerings and were impressed. My DS (4yo)was amazed by the turn down service and when asked where he wanted to stay on our next trip he said, "Animal Kingdom, that's where we always stay."
As a side note, one of the male concierge cast members does a terrfic Donald Duck voice

You pretty much can't go wrong with your choice and you might enjoy splitting your trip between resorts.
Good luck!
