text: I played around a little with this area. I didn't find anything in the web referring to P5 and P6 as parking areas. Besides the VoGIS satellite images I only found one picture to verify things:

  So I moved P5 to the part which you can see on the picture. Didn't touch P6, if it exists like this I guess the position is completely wrong. Therefore I don't thing it make sense to connect it. On the meadow left (and up along the rode) of the "Schihütte Mellau" seems to be parking in the winter time. Maybe that's one of them. I would rather delete it than having it flying around like this until someone can actually confirm at least a rough location.
