Dawlish Notices

It's my father-in-law's 85th Birthday very soon and I'm trying to find out any information I can on the place where he and my mum-in-law stayed in Dawlish on their honeymoon, 53 years ago as a surprise for him.
The guest house was called GLENDARAGH (Sorry if the spelling is incorrect!)
I've tried more or less everything I can think of to try and find this place to no avail. If anyone can tell me what happened to it or if it has changed it's name etc, I'd be really grateful.
Many (hopeful!) thanks!
