Either way you should (I know availability will dictate) have your own room, I have done two IR's and both times I have had my own room.. I know people will try to tell ya different, but if you have a supervisor with a big set he/she will sort everything out. It is one thing to be single and wild living in Nelles, than it is to be on an IR married and being surrounded with wild roommates... I know in Halifax if you are on IR you could get put up in an furnished apartment/hotel.....
My story is when I first got to ESQ I was posted to the VAN (AB), my clerks in halifax knew I was going on an IR, but neglected to inform me of my entitlement of a room.... SO I lived onboard until the Clerks found out, the ships office set me up with a room in Nelles...... I went to move into Nelles, and I found that I was in a room with 3 other dudes..(when I questioned the accommodations personnel they told me that there were no empty rooms..)..... NOT COOL, this was on a friday, I stayed onboard all weekend, then come Monday one of the clerks inquired about my room, I informed them that there were 3 animals living in it.... She snapped, made a phone call.... I had my own room before lunch, which was empty and ironically right across the hall from where they originally had me booked. Same thing in Halifax (as a LS), at first it was "a" block, after a quick discussion with accommodations personnel there, they quickly changed my room to St. Laurent block...........
Be polite, professional, and hopefully you will catch a break and get your own room.
Good Luck!
Stoker eh? GO BOATS!!!
