Richard, we have used the Chertsey CCC site at new year (and at other times and will be spending Xmas here this year). The site is right by the river. They have a clubhouse on site and arrange events. However, when we went we went to the Bridgehouse hotel / pub, which is just outside the gates, whee they had an enjoyable dinner dance. Just over the other side of the bridge is another pub, the Kingfisher. There is also a pleasant alk along the river (ideal if you have a dog) to Shepperton Lock where there is a pub.
