Concern Regarding Toilet Access Codes

Lindyloo

Hi, I'm not sure whether I am posting this in the right area but I thought I'd mention my concern.  We are going to the Houghton Mill site in the near future, and this evening I accessed the site details prior to logging into the CC website.  I then went
to download the site map, and noticed that the toilet access code was displayed on it.  I've never been to Houghton Mill before so don't know how easy it is to access the site by foot, but in my opinion, what is the point in having a code if it is available
for every Tom, Dick and Harry to see.  Is this a safety concern, as you never know who might get hold of it?
