B & B Inn America Reservations
http://bnbreservations.com/
This site has only a few listings with descriptions of B&Bs in the U.S. The site allows you to ask for reservations based on city, state and desired accommodations. The site allows you to request information about concierge services, car rental, and pet accommodations. They also offer recipes, a gift shop and a newsletter, but they need to develop these services more as little information is currently available.
