i really want to get into les prince so I'm wondering if i choose a room that has a washroom then maybe i will end up being in the les prince hall forsure

I don't know if it does, but just picking a room with a washroom isn't enough to guarantee les prince. As long as there's even one other room in any other Rez with a bathroom (there is) then you might get that one.

There's no guarantee you'll get a room with your own washroom at all, despite ranking it #1. But don't worry, you will adapt to whatever you get!

I had a double with a washroom in Matthews in 2007/08. There is a few around here and there (I think mine was the only one in Matthews that wasn't reserved for the HCA/HPA)

if it is a random lottery wont that mean there no hall where it is all first year students

I think if you put double room with washroom as your #1, you'll most likely get Les Prince if you're selected early on. There probably are the odd room here and there that have a double room with washroom in other residences, but Les Prince has the majority. So its probability i guess.

McKay Hall had some double rooms attached to the bathroom on each floor.

moulton has one single room with washroom on each floor, but last year, 1 was reserved for the hpa and one was reserved for the hca, so there were still two single with washroom for everyone else =P
