Before we started using sites like Booking we would arrive in a village and go to the TI and ask them to book a B&B for us. Is there a site for the Cotswolds that we can book B&B s in peoples homes in advance?
Many small/local B&B are on the major sites like Expedia now. The only one we booked separately for our trip in September was in Wood Stanway. We contacted the owners directly based on the information on their website. I’d recommend getting a small Cotswold Way guidebook, as they typically list out all the available accommodations in various towns. AirBNB and VRBO are other sites where you can look for in-home accommodations in specific locations, although these typically won’t be B&B-type experiences.

Often, if you search for Tourist Information and a location you’re pick up local and less (or non?) commercial listings
