Mickey_k, I have stayed at both resorts. My favorite resort, however, is the AKL (followed by the BW).
I stayed at the AKL with my husband, teenaged son, and daughter last Easter. That is when I fell in love with the place. For my holiday stay, I just had to share that resort with everyone who was vacationing with me (parents and sister's family). Even though the GF is my husband's favorite resort, he thought everyone should try the AKL, and thus I booked reservations there. Needless to say, the AKL was a hit with my family and everyone had a wonderful stay.
Now, that is me. That is not you. Only you know what is in your heart. If you have always wanted to stay at the GF, then by all means stay there. However, if you are torn, then try to decide where you think your daughters would like to stay.
I can tell you that my little daughter adores the AKL's kids' club -- Simba's Cubhouse -- and begs (yes, begs) to stay there each vacation (she even convinced my nephew to attend Simba's with her one evening and they had a ball). She also loves the AKL's pool area. They have wonderful activities there during the day for the kids (arts & crafts, pool games, etc). And rocking in the rocking chairs out by the fire pit during the evening, oh, it is the best way to relax and chat with the other resort guests. Storytelling out there in the evening is excellent, too.
Look deep into your heart and the hearts of your family and decide what you really want to do. And don't worry, the other resort (the one that you don't pick this time) will be waiting for you during your next visit.
