stadium equaling 35% of the stadium's capacity, along with hotels for the teams, officials, media, and other dignitaries. (For Super Bowl XXXIX, the city of Jacksonville docked several luxury cruise liners at their port to act as temporary hotel space.) There must be practice space of equal and comparable quality for both teams within a twenty-minute drive of the team hotels, and rehearsal space for all events within a reasonable distance to the stadium. The practice facilities must have one grass field and at least one field of the same surface as the host stadium. The stadium must have a minimum of 70,000 fixed seats, including club and fixed suite seating, during regular season operations. Much of the cost of a Super Bowl is to be assumed by the host community, although some costs are enumerated within the requirements to be assumed by the NFL. New Orleans, the site of Super Bowl XLVII in 2013, invested more than $1 billion in infrastructure improvements in the years leading up to the game. The NFL finds backup stadiums for the Super Bowl every year, in the event of a last-minute relocation of the game. Home team designation The designated "home team" alternates between the NFC team in odd-numbered games and the AFC team in even-numbered games. This alternation was initiated with the first Super Bowl, when the Packers were the designated home team. Regardless of being the home or away team of record, each team has their team logo and wordmark painted in one of the end zones. Designated away teams have won 32 of 57 Super Bowls to date (approximately 56%). Since Super Bowl XIII in 1979, the home team is given the choice of wearing their colored or white jerseys. Originally, the designated home team had to wear their colored jerseys, which resulted in the Cowboys donning their less exposed dark blue jerseys for Super Bowl V. While most of the home teams in the Super Bowl have chosen to wear their colored jerseys, there have been seven exceptions: the Cowboys during Super Bowls XIII and XXVII, the Washington Redskins during Super Bowl XVII, the Steelers during Super Bowl XL, the Broncos during Super Bowl 50, the Patriots in Super Bowl LII, and the Buccaneers in Super Bowl LV. The Cowboys, since , have worn white jerseys at home. The Washington Redskins wore white at home under coach Joe Gibbs
