There are other parts of Palawan that isn't so touristy yet like Port Barton (but getting more popular now) that you can check out when you visit the PH. Hopefully things improve. I think local tour operators are aware of the possible shutdown/rehab of parts of the islands if it gets worse and they don't want that to happen.

I agree that we shouldn't tolerate this behavior. I was just so happy to join a group outside that hostel that were unlike them. :)
