Yes, he said you have to be a BCMC member to get the key as they don't want Mountain hut area to become a three ring circus. Fair enough I guess.
Agree with this. I stayed in the hut 2 nites (as a non-member) at a time, and it was free with voluntary donation only. It is a nice hut. One can camp easily at many spots nearby, there were just too many mozzies & hut was better option. Had it to myself 1st night, and 2nd night shared with BCMC guy, forgot his name, and had a nice chat. Good times.
