Station at Ribblehead. Golden Lion at Horton-in-Ribblesdale. Both been used by our lot and are amicable to a session in the main room. Not sure if they can cope with 30 as our mob usualy number about half that.

Hill Inn as mentioned by Les - Make sure they do not have an event in the barn when you are there though. The old landlord had a spate of running heavy metal concerts but I think the new one is a bit quieter:-)

I have a friend who runs this hotel in Ulverston but I have not seen it yet so don't know how it's laid out - We are not going until March.

Good luck whatever you find.

Cheers

Dave
