Haven't actually stayed at AKL yet, but we did look around it on our last trip. We absolutely LOVE WL, and from what I've heard we are going to absolutely LOVE AKL too - so my vote was for 3 of each. That's what we're gonna do on our next trip -- except that we are gonna try Poly instead of WL (totally out of character for us WL fans). I think 3 at each will give you a nice, well-rounded stay. Just make the most of the proximity to MK, Epcot, and monorails while you're at WL. Then make the most of proximity to MGM, AK, and Downtown Disney while at AKL! No matter what you choose, I think you'll have a wonderful time!
