Bovey Castle was once known as the Manor House Hotel ... which I visited in December 1982 and reviewed in The Confidential Guide. It only got a 3 back then, as Mark Pearce speculated it might. I'm sure the conditioning has much improved with the new ownership, I don't know about the architecture; my review was pretty much the same as Mark's.
I think your idea of seeing other Abercromby courses is a major plus and I would be very interested to hear about them. It brings to mind Robert Hunter's preface to THE LINKS:
"How pleasant it would be to take from our shelves a book of Abercromby's courses and to study at one's leisure his ingenious and delightful art, as we have seen it, or someday hope to see it, at Worplesdon, Combe [sic] Hill, and Addington!"
