yes, the problem is with too stupid routing software. Routing to the
nearest street of a centroid works well for small areas but can completely
fail for big ones.
Heuristics will solve 90% for you - Normal buildings and a single

it is already linked spatially. What you have to do is map the campsite as
area and map the reception within this area. Similarly for the parkings.
Routing software should solve this contextually. If I am walking I want to
be led to the main entrance (or given the choice which entrance), while
when I am driving I will typically want a parking. A parking must not
necessarily be inside the area, it can also be close by.
