It really depends on your family and what you will enjoy. We have stayed at both WL (last month) and AKL (end of May) recently. While I enjoyed both, I enjoyed AKL far more. It just seems more exotic and definitely more peaceful. While the boat from WL to MK was different, the novelty quickly wore off (rain and heat/humidity sped up the process, too). The rooms at WL also seemed more worn (although I know they are beginning to refurbish them). Our view at WL was supposed to be pretty good -- we could see the fireworks in the distance. However, other than that brief 10-15 minutes at night, it was pretty darn boring. Back to my original statement, my cousin and her family of 4 prefer the lake view at WL. My 3 children, dh, and I prefer seeing the animals at AKL.
