Harry, Hermione and Ron never use the tent Bill Weasley lends them, not even for one night. The morning they leave shell cottage is the same day they break into gringotts and then escape on the dragon afterwards. They're on the dragon till around sunset, then Harry has his vision and they rush straight to Hogsmeade and not long after to Hogwarts though the Hog's Head passageway. ~Hayley~
