Goldsmith (and Roehampton) -Journalism- Someone please help.

Okay so i have gotten four offers so far, UEL, Bangor, Goldsmiths and Roehampton; Roehampton and Goldsmiths are the two particularly that has my interest (it's for journalism undergrad) Goldsmiths accommodation has a deadline for tomorrow and i need to make it my firm in order to make an application for it. Roehampton would probably be my insurance then i have the 14 day cooling period to switch it up if needed. However the thing that is putting me off Goldsmiths is how expensive accommodation as i wouldn't have any help from parents and would struggle when it comes to affording food etc.. Roehampton has a more affordable accommodation situation and they also don't have a deadline for applying. The open days are next weekend for goldsmiths which i am attending then i'm going to go to roehampton to look around also to see which i feel; more comfortable at. Can someone tell me the best thing to do in this situation? would be greatly appreciated, or if you're doing Journalism at other of these courses please inbox me as i have questions!
