If you have car hire would they charge extra for you to go to Aberdeen instead? It might mean you can travel at a more reasonable time in the morning albeit from a different airport. I dont think the distance between the two is huge and if you have a car? just a thought which may help....

Can understand why you want to make the most of your last morning - how about looking at flying in to Birmingham or as above travel from Aberdeen? It will mean paying out a bit but I cannot imagine it would be anything too harsh on the credit card and would mean you get to enjoy breakfast without such a rush.
