To celebrate its 10-year anniversary, AmericanAirlines Arena, the home of the Miami Heat, is inviting fans to sit down.

Well, sort of.

The arena is hosting a “Sit-In” contest on Dec. 4 to win four tickets to every event – Miami Heat games, concerts and family shows – at the venue in 2010, starting with the Phish concert on New Year’s Eve. (If a show has multiple dates, the winning team wins four tickets to one of the dates). The package of tickets is valued at about $35,000. Parking, however, is not included.

Teams of four are to compete by sitting in every seat for no more than five seconds each in the 19,600-seat arena within 24 hours. People who sit for longer than five seconds will be disqualified.

Teams must include at least two people, but no more than four. Only one team member can do the sitting at one time, but is able to tag the next sitter on the team when he or she is ready to switch. Arena staff will monitor the participants. As of Wednesday afternoon, more than 70 teams had signed up.

If more than one team completes the task, a Heat trivia contest will determine the grand prize winner. A trivia contest will also be held if no team completes the task. Eligible teams at the end of the contest that don’t win the grand prize will receive six-game partial Heat ticket plans for the 2009-10 season for each team member. And team members that sit in every seat in at least three pre-determined sections will receive two tickets to a Heat game this season.

To compete, teams must register by Dec. 3 at AAArena.com. The contest begins at 8 a.m. Dec. 4.

The arena opened with a Gloria Estefan concert on Dec. 31, 1999.
