From the Story
Discovered in Book 4, Chapter 7, Bagman and Crouch
"The Weasleys' camping spot is located on the very edge of the wood, at the top of the large field. From the outside, their tents look like ordinary, slightly shabby Muggle tents. Inside, however, they are huge: the tent Harry enters is an old-fashioned, three-roomed space, with a bathroom and a kitchen.
Many of the tents at the campsite near the Quidditch World Cup look almost ordinary, their owners clearly having tried to make them as inconspicuous as possible. Some of the tents have been given chimmneys, or bell pulls, or weather vanes, their owners not quite understanding the limitations of Muggle tents. Here and there, Harry sees tents so obviously magical that they can hardly fail to make Mr Roberts, the Muggle campsite manager, suspicious. Halfway up the campsite field there is an extravagant confection of striped silk, which looks like a miniature palace, with several live peacocks tethered at the entrance. There is also a tent that has been given three floors and several turrets, and beyond that there is a tent with a front garden attached, complete with birdbath, sundial and fountain."
