Haha, who better to ask (for an opinion on the necessity of feminine modesty) than a bunch of middle age blokes
There are separate shared bedrooms in two huts, a drying room in one. The rest are 'open plan'. Toilets, if you can stand the stench, have hanging hooks though thats all i'd touch, the hooks. The smell is more bearable late in the day/ early AM.
You can get Telstra reception
on the track from a number of high points of the first three days (heading south) and usually from Narcissus area. Other than needing reception, I use my phone a lot as well, apps, books etc. As for charging, well, while technically 'possible', no, no ports supplied in huts... though there always seems to be some loud geezer with the bottled variety
Personally, i'd avoid the huts, you can go to the local backpackers for similar. Camping only enhances the adventure, experience close encounters of the furry kind, surviving 'blizzards', counting stars etc etc Wholesome, scout badge type fun..
Have Fun
