We usually go to Woolley Grange over the aug bank hol and I booked it as we left last year and promptly forgot about it. Just realised this morning that we can't go (and we're in for cancellation charges which hurts even more). They seemed pretty confident they could get rid of it, but thought I'd offer it on here as well - it was Saturday 25th for three nights in west gable, a pretty double room with a large bathroom that takes two zed beds and a cot quite easily. Rate is £300 dinner bed and breakfast and the pool is hotter than a bath.
You'd need to call them direct 01225 864705 but you should get the 10% discount for Mumsnetters I think.
