Here's a thought - how about cooking courses as well? One spouse gets sent out on the bike, the other learns about top quality food from an M* chef. Kitchen space might be an issue, but there is any amount of secondhand professional kit available at the moment.
Themed holidays are always a good way to increase your market. A friend of mine has just thrown in his job as a bank manager and opened a B & B in Provence. His wife paints, so they do watercolour and oils weeks. Neither of them takes photos, but they have a link with a local photographer. Same with a local Yoga instructor.
Sorry to be stating the obvious, but there are squillions of B & Bs around, even in rural Wales. What you have to do is to give people a reason to stay at your B & B; and to come back next year.
I know the term 'business plan' scares a lot of people but it's really very simple. You can spend fortunes on professional advice to do these things or you can apply a bit of common sense
Where are you now, what do you want to achieve and what is necessary to get from A to B, that's a business plan. The depth and detail are what seperate a 'bag of a fag packet' scribble and a template that you can constantly refer to and refine. A well worked plan will become a working document that can evolve, and remain, with the business for it's entire lifespan. If you ever need a bit of help from the banking world it also eases transactions hugely.
