Hi Eb,
You may need to do more than that, ie appeals and zoning IF they will even consider it, many places do not even want B&B's in their town or city. Go directly to the city itself, in person and get the info (in writing) what needs to be done.
I wouldn't contact other B&B's cold calling, they probably won't appreciate it, and in fact if you can't find it online, then I bet there isn't a B&B association there. PS I have had people calling this way "We want to open a B&B can you tell us what we need to do." Unless you pay them for their consulting time, then you are wasting their time, just an explanation of why they prob didn't call you back,
All the best with your plans!
