You know, in a little wooden pod thing? I'd link to it if I could make it work, but I can't!
Think of something the size and shape of a 6 person tent, but made of wood. Apparently you take absolutely everything else with you: airbeds, sleeping bags, stove etc. No electricity.
Have booked for a couple of nights as I liked the idea of camping without the stage where DH gets a right gob on struggling with the tent.
