Hi Mark
In answer to your request, I would like to offer my little website for inclusion in your listing. Needaloo I have spent over two years locating and listing as many of the disabled toilets in the U.K. There are over seven thousand listed complete with a link to Streetmap showing the location. As I am disabled myself I have not been able to visit them all to check for accuracy, I have included various ways of contacting me to put me right on where the Streetmap arrow should go.
Regards
