I will be in Israel next month on vacation. I am staying mostly in youth hostels in the male dorms because that was what's in my budget. I am in my early 20's, and I have tried to research and book the safest and cleanest places possible. However, I'm slightly nervous about staying in a dorm full of guys I don't know. Is there anything I should be aware of? Obviously, I know to be polite and considerate of the other people. Have any of you stayed in a single sex dorm, specifically a male one? What is some good dorm ettiquette, what should I expect, and how do I keep myself and my belongings safe?
Also, and this may sound dumb, is it alright to sleep in one's undergarments in a same sex dorm or should I be more conservative? How "open" are these environments? I'm not trying to be offensive with my questions, but I honestly would like to know before I go on vacation and don't know who else to ask.
Thank you so much.
