Hi Max's Mom!
I have never been to either but I've done emmense research on both because those were the two we were choosing between too! We were also concerned with AKL being so far away. I knew we definately wanted the afternoon breaks since we have a four year old, yet we'd also want to do dinners and breakfasts. We decided on BC for two reasons: 1.) We were just a hop from anywhere and could easily fit in a break without spending too much time on a bus/in a car. 2.) Our DD LOVES swimming and we'd heard that SAB at BC was absolutely wonderful! We hadn't heard that many wonderful things about AKL's pool area. We decided to try AKL when DD is old enough to appreciate the animals without missing the familiar foods and killer pool area.
Just my two cents worth, hope it helps!
