I agree it comes down to theming and its hard to compare the resorts in that area. If you will use the amenities you are paying for or rather they are important to you, then go with WL. For example some people cannot take a moderate because of the exterior corridors and lack of balconies. To some people they feel very motel-ish. Now I don't feel that way at all and so am happy to go moderate. I loved CSR, it has the more tropical theming which I like, I loved the lake, the main pool was awesome and the whole feel of the resort really appealed to me. CSR also has some nice amenities that other mods don't like a room service menu, spa and health club.
For me personally, both the WL and AKL can never justify me spending the extra money because the rooms are not that much bigger than a mod room. Other people see it totally different!
If the theming appeals to you and the extra money doesn't bother your budget go for the WL. I wouldn't base a stay anywhere on transportation issues alone as all the resorts are hit or miss in that area in my book.
