I smoked out of bongs all the time at school.

If you're concerned, you could just bring a pipe until you meet some fellow potsmokers and can chill with them.. I definitely wouldn't roll up on the first day and whip the bong out.

It also depends on the size of the bong.. I had a small one in the dorms that did me well (probably about 6 inches) but 2 feet is kinda big to keep hidden.

Not to mention health and safety inspections.. so yeah, I suggest bringing a pipe or just papers and surviving off those till you meet someone who can keep the bong at their apartment (that's what I did).
