Thanks Gaildorfblues, I'll take a closer look at those sites, but initially they look very useful. :-)
Thanks for the tip puntospilot, but I'm not on Facebook - too old. :-)
Might be worth joining Facebook just for the extra info in the short term. Quite a few groups on there full of useful info.
There are the usual sites you probably already know about that generally require membership like https://www.iccc.ie/ or even http://www.safenightsireland.com/ Try asking on https://www.boards.ie/ they have caravan and camping sections.
