gap between the Apollo and Space Shuttle programs, attendance remained at over one million guests and it ranked as the fifth most popular tourist attraction in Florida. When nearby Walt Disney World opened in 1971, visitor center attendance increased by 30%, but the public was often disappointed by the comparative lack of polish at KSC's tourist facilities. Existing displays were largely made up of trade show exhibits donated by NASA contractors. Later that year, a $2.3 million upgrade of the visitor complex began with added focus on the benefits of space exploration along with the existing focus on human space exploration. In 1995, Delaware North Companies was selected to operate the visitor center. Between 1995 and 2007, the visitors center went through many changes, including the improvement of restaurants, retail shops, buses, and new exhibits. It is also when the visitor complex got its current name, Kennedy Space Center Visitor Complex. Since then, the facility has been entirely self-supporting and receives no taxpayer or government funding. Kennedy Space Center Visitor Complex was voted the 8th best museum in the United States by Trip Advisor in 2016. The Visitor Complex has had a visitation increase in the 2010's, in part due to the addition of the Space Shuttle Atlantis on display, the decreasing popularity of nearby SeaWorld due to changing attitudes to welfare of animals in captivity as KSC was considered an alternative, and the increasing interest in STEM fields for children. NASA renewed the contract with Delaware North Companies through 2028. Attractions Included in the base admission is tour-bus transportation to Launch Complex 39 and the surrounding KSC property, and the Apollo/Saturn V Center. Previously, it used to include admission to the Astronaut Hall of Fame, to the west. That building is now closed and the U.S. Astronaut Hall of Fame resides in a new exhibit at the visitor complex, Heroes & Legends. The Apollo/Saturn V Center, located north inside NASA's gates, is a large museum built around its centerpiece exhibit, a restored Saturn V launch vehicle, and features other space related exhibits, including an Apollo capsule. Two theaters allow the visitor to relive parts of the Apollo program. One simulates the environment inside an Apollo firing room during an Apollo launch, and another simulates the Apollo 11 Moon landing. The tour formerly included the Space Station Processing Facility (SSPF) where modules for the International Space Station were tested. The
