I am with Gott & Wynn. Couple of years ago I intended going to the Curgurough Taster Day but it was snowed off.
I checked with G&W who said ok, no extra cost. I can't remember actual details of cover, but think the excess was raised a bit.
I was a bit amazed at this but they confirmed it so gave details for their record out of courtesy and good will.
Not needed in the end but nice to know.
