There are two possible views you could have when you book Standard at WL. In my opinion, it is only worth it if you request a lobby room. These look out over roof peaks. Otherwise, the view will be of the service area. If no lobby rooms were available, I'd rather stay Standard at AKL, as I've heard those rooms may face a parking lot but not an actual service area.
Edit: One possible advantage of a Standard view at WL that overlooks the service area is, if you are on one of the highest floors, you may catch a glimpse of the Wishes fireworks.
