As I side project, I've been working on something to solve this: For ski resorts, 2D maps loose a lot of detail and have a lot of compromises (but are easy to understand and navigate). 3D maps offer more detail but are a pain to navigate and are often disorienting for non-technical users. My thought is a "2.5 degree" hybrid map. One that maintains the important 3D detail but keeps the navigation "on rails" so as to make everything easier. I'd be curious to know your thoughts on this, keeping in mind that this would be targeted at casual users and probably not HN types (HN types probably have no problem navigating/groking a true 3D map).
