The world’s largest Legoland is on track to open in Florida this autumn, and become the group’s fifth park, following other openings in Denmark, Germany, the UK and California.

Central Florida’s Visitor and Convention Bureau confirmed that Legoland Florida, a 150-acre park in Cypress Gardens will officially opens its doors on October 15.

The park’s management has confirmed that it will have more than 50 rides, show and attractions, including roller coasters and race cars described as “pink-knuckle”.

However the exact nature of many of the attractions remain secret.

Other features will include a series of family-focused shows and attractions, along with one of the large Lego retail store, a 4D, 700-seater theater, and a clubhouse where kids can play LEGO Universe, the brand’s Massively Multiplayer Online Game.

It is also believed that several of the attractions at the existing Cypress Gardens site, which was previously a theme park, have been remodelled for Legoland. This includes a flight school ride

The first Legoland opened in Copenhagen in 1968. After Florida, the next opening is set for 2012 in Malaysia.

According to the Themed Entertainment Association’s annual report, Legoland’s European parks are among the most popular in Europe, with Legoland Windsor receiving 1.9 million visitors in 2010 and Legoland Billund in Denmark welcoming 1.65 million.
