William only got 30 minutes of sleep the night before his wedding. "[The crowds] were singing and cheering all night long, so the excitement of that, the nervousness of me and everyone singing — I slept for about half an hour," the royal revealed in a 2012 documentary. "The hardest thing was trying to walk down the stairs with my spurs on, sideways. I had visions of myself and my brother [Prince Harry] colliding and crashing down the stairs."
