I actually view the Carstensz Shelter as a good thing, not because I like mountain huts. In fact, I prefer to sleep in a tent rather than a noisy crowded hut. However, it sounds like they are finally trying to attract climbers rather than chase them away.
The single biggest risk when climbing Carstinesz is that your group will get turned back by one of the myriad of local government entities because you didn't have all the right permits, or that your guide would abandon you during your trip. Imagine shelling out big bucks and taking time off of work only to have your trip canceled because of a bunch of thugs. No thanks! If the creation of the guest house brings with it the consequences of having a more stable / less risky bureaucratic environment there, then I welcome it.
"There have been thousands of foreign tourists who wanted enthusiastically to climb up to Mount Carstensz's peak but because there was no infrastructure, especially a guesthouse, they canceled their plans to go there," Werner said.
Bullshit!! People are afraid to go there because of the high risk of being turned back by corrupt authorities or the mining company, and/or that your lousy guides will screw you - not because of the lack of a hut!
