If you want to go, you might as well apply. At least then you can say you tried. If you don't apply, you definitely won't get in, but if you do, at least you stand a chance.
If you're really against it, Durham is the 'oxbridge reject' uni. So many people rejected from Oxford or Cambridge end up there.
Scotland generally is really nice, and lots of the uni buildings do look lovely.
If you like Oxford and/or Cambridge though, you might as well try. You still get 4 other options and literally worst case scenario, you can use extra/clearing, which will have lots of good courses.
If you're doing music/drama/dance it might be worth looking into conservatoires. Lots of them have really nice buildings. I'm going to Trinity Laban, and the music building is so lovely. I know it's similar for other London ones and I think the RCS.
