Why are you dismissing Glasgow and Queens?
There must have been a reason you applied there originally - why did you? Have you been and visited, read the prospectus and properly found out about these universities? If you've done all of this and really hate them, then fair enough, but you need to make sure you're giving them proper consideration before rejecting their offers. I went to Edinburgh but Glasgow was my insurance choice and I would have been more than happy to go there, the university structure is the same in that you do 3 subjects in 1st and 2nd year, Glasgow university is prettier than Edinburgh and they're both great cities. The student accommodation is very similar too. Yes, Edinburgh will always have that pull of "its Edinburgh" but Glasgow is equally as good. There is very little that you'd get living in Edinburgh and going there than if you were living in Glasgow and going there, its all down to perception. Similarly, Queens is also very good and again, a good city and pretty buildings (if that's what you're looking for) so I'd advise you to properly research these options before turning them down.
At this stage, wait and see what Edinburgh reply with then make your decisions on the basis of this aspect. If you really don't want Glasgow or Queens then you can consider looking in clearing. Exeter still have history at their Cornwall campus with joint honours available at their main campus, so this is something to consider. Alternatively, you can accept one of your offers then see what happens on results day. Then, you can either decline the offer and see what there is in clearing (although unlikely for the universities you're aiming for) or reapply next year if you decide you don't want to go to that choice. Either way, you need to keep your application open so that you're eligible to use clearing and keep your options open.
If you do reapply remember that nothing is guaranteed. Reapplying for the sake of a couple of very competitive universities, even with top grades, might end up in an even worse position than you're in this year and even if you were to reapply to Glasgow, for example, there isn't a guarantee you'd get an offer again. If you reapply you need to be totally prepared that this time next year you'll be in the same position. If you're happy with that as its better or the same than what you feel you have now then go ahead but otherwise, consider it properly. That said, there's no point going to a university you're unhappy with simply due to the fees, as it'd be likely you'd drop out and end up with more debt than if you'd just waited a year and paid the extra fees.
