As long as you aply on time you will be fine! I got into Hull through clearing...best decision I ever made =D so applied for accomodation really late and it was either a shared room or a room in Thwaite Hall without ensuite! Decided on Thwaite Hall and got an lovely room :-)
I totally recomend living in halls especially Thwaite..not being biased but I think it is the nicest hall! I defiently think its worth sacraficing an ensuite to get a non shared bedroom! I've never had to waitaround to get a shower...the bathrooms are always clean and normally theres never anyone in there anyway!! The atmospheres fab and you dont have to cook!!! If you do have any questions about hull I can try and answer them =D
