I have been, several times: the lodges bunk by gender, guys in one room, girls in another. It is better than sleeping outdoors, and usually, 99% of people are totally exhausted, so whatever sounds or odors there are are not an issue. If there is bad weather, the place will seem like the Ritz. Also, I hiked up Mt Washington when I was like 25; it is a tough hike, even in summer. The tree line is like 2,000 feet below the summit, so you are very exposed. But it is amazing place!
