Matterhorn in summer 2014 : Hornli from Schwarzsee

Posted as guest by Guillaume-colocasia:

We plan to climb Matterhorn via the Hornli ridge in August 2014. But, Hornli hut is closed.

Is anyone knows what is the best solution:
-starting from Schwarzsee to go to the top via the Hornli ridge?
-sleeping next to Hornli hut and to the top via the Hornli ridge?
-climbing via the Lion-Hornli traverse?

Thanks

Guillaume
