Arthur, obtaining a schengen visa as the spouse of a British citizen is very easy and for once is actually free.
They can't ask for any real details about your trip and I don't think they can refuse to grant a visa without a very very good reason. You probably though would need to visit Edinburgh where many EU countries have a consulate (including France) to apply - you could check to see if any of them accept postal applications. Also they tend to grant 6 month multiple entry visas so you can take more than one holiday if you desire. Prior to my wife getting British citizenship she obtained a schengen twice - once though the French embassy and once through an Italian consulate.
Obtaining a schengen when you are not a spouse of a British citizen is more difficult. It's not free (60 euros I think), they tend to require confirmed travel plans and will often only grant a single entry visa just for the planned trip, and they can and will refuse you.
