For me who has seen many of these backstage buildings from the “Wildlife Express” train ride in person. I have seen all but the hippo and crocodile areas. Not to mention I have also seen the cheetah and warthog backstage areas as well, (However I will have to see them again in person just to be sure).
I think that some people skip the Wildlife Express because it is perceived as a kids train ride to a children's area (Rafiki's Planet Watch), which it is. But skipping it also misses these areas. I actually like the train ride, and it often is not crowded like everything else.
Next time I go to DAK I'm definitely riding the train so I can see some of these in person
It's fast, and some of the views are obscured by plants and such, but it is a nice ride, and the train and stations are actually pretty cool, if you are into that too.
