A lot of theme parks are going down this route and I hate it. My biggest gripe is that it seems to eliminate the human factor of navigation using landmarks to get around. Most people will plot a mental path in their mind and use prominent features on the map to determine whether they're going the right way but with this 3D blob and some of the other parks hyper-real isometric monstrosities it makes it really hard for the lay person to get around.
Its why if you look at Disney park maps they're not accurate to scale, but they have large exaggerated features that you would naturally use as a point of reference when navigating the park and there is a lot of contrast between what is a walkway and what is not. This may not be a problem in smaller parks as eventually you'll get to where you need to go, but once you to scale up it becomes a nightmare especially with Australian park hours being very limited.
I just feel a lot of parks have fixed something that ain't broke, and broken it in the process.
