The Dementia Services Development Trust (www.dementiatrust.org.uk) were signatories with the Residential Forum and many others on the coalition on visiting in care homes.
They have asked me to send you a link to a film drama that they have made about the visiting issue, hoping that you might view it and engage with the contents.

A short promotional clip is here https://youtu.be/9ZWfE9cnoU8
And the film is here. https://dementiatrust.org.uk/projects/take-me-with-you/
