Not at all precious not to want to share.
I suppose one upside might be if the other person moves out you then get a huge room (with a spare bed) and en-suite to yourself.
DD chose her college because she wanted to be self catered and liked that it is a shared kitchen with 6 en-suite bedrooms all over the college so no wondering about what type of accommodation.
But I'd hoped that they would let them make contact with the people they are sharing with-if nothing else they don't need 6 frying pans, 12 other pans, 6 can openers... taking up space in the kitchen.
She's rightly pointed out that giving contact details, or even names would be awkward under the data protection act.
What they should have done was ask them on the form they filled out for room allocation if they were happy for contact details to be passed on.
We're off to Ikea tomorrow. Not sure she actually needs anything, but apparently it's the right place to go before going to uni. I've never been and not sure that's a bad thing. 
It still seems quite a long time before the 29th (or 28th she'll need to leave). Durham must be one of the latest.
