It attracted 1.1 million visitors for its first season, but that decreased to 560 to 580 thousand the next season Alfa filed for bankruptcy reorganization in February 2002. The park was not profitable, as Alfa SmartParks specialized in running water parks and smaller amusement arcade centers. In addition, the park had common amusement park spinning rides and a carousel merry-go-round. The park had a log flume called Cypress Plunge and a splashwater falls ride called Spillway Splashout. Other rides included a junior steel coaster called Rex's Rail Runner, a wild mouse steel coaster, and a common steel shuttle looping Vekoma boomerang rollercoaster called Zydeco Scream.
The intent was to rebuild the Zephyr, but it was a smaller roller coaster, so that idea was scrapped in favor of the current larger Mega Zeph. Mega Zeph was inspired by the old Zephyr roller coaster at the closed Pontchartrain Beach Amusement Park that was next to Lake Pontchartrain by the University of New Orleans. Rides included Mega Zeph, a wooden roller coaster track built on a steel frame to prevent termite infestation and withstand hurricane-force winds. The original themed areas were Mardi Gras, Pontchartrain Beach, Cajun Country, Jazz Plaza, Kids Carnival, and The Goodtime Gardens the first season ran until October 29, with season passes available for $89.99 (individual) or $219.96 (family of four). It was operated by Alfa SmartParks, a Greek holding company that purchased the Odgen Entertainment theme park division the company has since changed hands and now is known as Palace Entertainment, owned by the Spanish company Parques Reunidos. The park opened under the name Jazzland on the crowd was estimated at 20–25,000 people, and 75–80,000 season passes had been sold. The park is built on a concrete deck 4 ft (1.2 m) thick. The partners included Burroughs & Chapin, which withdrew in 1997, and Ogden Corporation, which sold its theme park division to Alfa Alfa for $148 million in March 2000. In 1995, the developers solicited a loan from the United States Department of Housing and Urban Development (HUD), initially in the amount of $15 million, to complete the park.
Tom and Dian Winingder spent almost ten years arranging the partnership that would open Jazzland.

An option to demolish and clear the land was explored in 2019 following complaints from local residents, estimated to cost the city $1.3 million. As a result, city officials became more diligent in securing the park and banning tourists, tasking the New Orleans Police Department with patrolling the abandoned site and arresting offenders. Videos and photos of the site have emerged over the years from thrill-seekers and YouTubers. Following several failed proposals to redevelop the site, it remains abandoned and in poor condition. The Industrial Development Board (IDB) of New Orleans owns the property and oversees redevelopment plans. Six Flags salvaged several rides and relocated them to other parks. It was closed eight days prior to Hurricane Katrina making landfall on August 29, 2005, and due to serious damage from flooding, the park never reopened. Six Flags invested $20 million in upgrades, and the park reopened as Six Flags New Orleans in 2003. It first opened as Jazzland in 2000, and a leasing agreement was established with Six Flags in 2002 following the previous operator's bankruptcy proceedings. Six Flags New Orleans is an abandoned theme park located near the intersection of Interstate 10 and Interstate 510 in New Orleans.
