Both are great resorts - you don't say if you have kids - I find WL very convenient to MK by boat and monorail via Cont
AKL is reachable only by bus so you can spend a lot of time on the road - closest park is AK
I would stay at WL for first part of vacation when getting to parks may be the focus, then spend last few days (3) at AKL which is a lovely relaxing resort.
