Thanks all for your advice.
We don't have any equipment as we are a new group and will be using personal equipment already insured as part of our own house insurance. The insurance company doesn't want to know about those as they were not purchased as part of the 'company' - what drivel!
Also I have never taken out insurance before for this, but the Hotelier have asked me too, I trust my group and have worked with them before (as part of another group).
redcrx - yes, I was thinking this, but the insurance company doesn't have a box for that type of thing. I've never found finding insurance so complicated and I really begrudge doing it as all those who are coming are all friends of mine.
I think the hotelier are being a bit jobsworth asking me for all this, but I guess they are safeguarding themselves!
