Looking to stay at a castle for one night. Any good deals?
I stayed at Dalhousie Castle one night. It was amazing! Not sure if they have a good deal, but it's a great castle. There's also a restaurant in the Dungeon which was a great experience. My room had the stone walls, and a amall turret room. I would stay again in a heartbeat! It's also haunted if you like that sort of thing.
Having enjoyed a stay at Stonefield Castle Hotel in Tarbert (Argyll / Kintyre), I will mention a caution that not all "castles" are really historic castles when it comes to hotels. Stonefield was built in the 1830s as a baronial country house. It was never a castle according to the generally accepted definition.
It was a bit of a thrill to be staying in a lovingly preserved property, and we were impressed by Stonefield's location on the shore of Loch Fyne with walking path to a small island, as well as the famed azalea gardens. However, the condition of the plumbing left something to be desired (toilet ran, shower dripped, water temperature impossible to regulate). Stonefield belongs to the Bespoke Hotels chain.
Apart from the usual websites, these travel articles from The Telegraph and The Guardian may give you a more impartial idea of what to expect if you book at a castle.

Sir Walter Scott's Abbotsford is now renting rooms. It's a fantastic place. I haven't stayed there but have toured it.
I didn't stay here but really wanted to: Glengorm Castle on the Isle of Mull. I ate at their cafe which was small but nice and walked around the grounds. There are sheep, highland cows and even some standing stones on the property and the views were amazing. It is my dream to return and stay there.
I have stayed at Glengorm on Mull, more a nineteenth century country house, but loved it.
