The University of Phoenix Stadium opened for business in August 2006, and that business is primarily as the home of the Arizona Cardinals of the National Football League (NFL). In addition to Arizona Cardinals games, University of Phoenix Stadium is the site of the annual Fiesta Bowl, and was the location for the 2008 Super Bowl.
The stadium tours take place on non-game days. It's a totally different place without 60,000 or 70,000 excited fans and when only staff is on the premises. Your tour guide will take you on a journey of the history of the Arizona Cardinals, and tell you how this state-of-the-art stadium came to be built. You'll hear about the people who made it happen, the costs involved, the design team, and the unique features of the stadium.
Stadium tours may have 5 people or 40 people on any given day. Tour guides are equipped with personal sound systems so everyone can hear. There is plenty of interaction with tour participants. My bet is that there isn't a question about the stadium about which your tour guide won't know the answer!
University of Phoenix Stadium Tour Tip: The tour is busiest when there are special events in town, especially related to sports. The Fiesta Bowl, Insight Bowl, BCS Championship Games, and even regularly scheduled Arizona Cardinals football games, when out-of-town football fans are most likely to be in the area, are busy tour days. Likewise, many visitors are in the area for Spring Training baseball games, so tours during March tend to fill up, too.
