Welcome to the forum.
This is a very different question and the first I am hearing of this sort…. I guess, if we were to find employment somewhere that will require (some) travel, would the journey to work, alone, be considered haraam? That being the case, it will be a situation where many muslim women by definition, find themselves doing something haraam.
On the all girl dormitory, I cannot say for sure as there may be further considerations as I have heard (not got it authenticated) that even in massage, a non believing girl cannot give massage to a believing girl… hmmm..
I am not helping very much… but still, here's to wishing you a great stay.
