I was called this past January when I did not renew and told they were doing some new things to draw more visitors to their site and to my listing. This was one of their plugs as the big city near me was being highlighted. I declined and said I would be watching to see how they improve their marketing and if I saw it had improved I would reconsider.
So now your post inticed me to do a little search. They have a nice write up on this Big city near me - a very popular tourist town BTW, and there are 22 B&B's listed on their site IN the city...I know of about 45 legit B&B's in the city, so lets just say they have about 1/2. Now one of the reasons to even have this Destination guide is to help drive a higher generic listing on Google for that city. I just did a Google search for big city bed and breakfast - and lanier sites do not show up in the first 10 pages and I gave up. - No sponsored listings either! This is sad!!!
If you are interested, I would do a search to see how the site is currently doing in your area. Call some B&B's that are listed - maybe in another market city that has been highlighted as a destination on their site. See if they mention any difference in traffic since the addition..
