at the top of the location tab put the full address of the campsite, and on the home page for the campsite include the contact details, is not straight forward finding contact details
many campsites can appear to be booked but when you call they have cancellations so it's always worth having telephone numbers
many of the campsite that are showing availability on your site are actually booked but that is obviosuly due to the campsite not updating their info.
i like the map and 10 mile radius search function
thanks for a very useful website, happy camping! Olivia
