The stately homes of Britain are a joy to behold. And if you visit a National Trust owned one, then there's always a nice piece of cake to go with your visit. I recommend the carrot cake.
But imagine wandering around these places without the other visitors. You could really explore the place, every nook and cranny. You could open every door and gaze out of every window. There would be nobody to tell you not to touch or to stay behind the red rope. What a taste of history you would have!
