We may get information that says that somebody received information about a hotel from a visitor information centre and then booked into it, but they may also have looked at the website. The chances are that they have done that, because people get information from several sources: they may get information from the visitor information centre and the website, and they may also have been sent a brochure in the post.We have to make a call on that, because we get three numbers for additionality.
