transportation to Jinsangling

Hello,
I would like to go there tomorrow or the day after tomorrow, depending on the weather. It's still unclear to me how to do this exactly. I tried asking the hotel, but they were of little use.

What I think I've learned so far: I have to go to Wangjing West subway station, and somehow there find a special tourist bus to Jinsangling? Does it take me all the way there or is there also a shuttle bus involved? And if I mis this tourist bus at 8AM, I have to take another bus, also from Wangjing West to Luan Ping and get of at the service area (how to recognize this?) and take a free shuttle bus? This shuttle bus only comes once every hour so I'll probably have to wait for a while?

Anyway, I would greatly appreciate it if someone could clear this all up for me, as I'm having some real trouble finding information about this online.

Thanks! :-)
Timo
