More than 1,000 companies from nearly 40 countries have reserved approximately 553,000 net square feet of exhibition space for IAAPA Attractions Expo 2015, making it the second largest trade show floor in the event's 97-year history.

According to the show's organiser, the International Association of Amusement Parks and Attractions (IAAPA), indoor space has sold out, and a limited amount of outdoor space is still available.

The exhibitors will showcase the latest products and innovative services in the global attractions industry to more than 18,000 owners, CEOs and managers from amusement parks, waterparks, family entertainment centres, zoos, aquariums, museums, science centres, resorts and more.

In total, more than 28,000 people from 100 countries will participate in the week-long event at the Orange County Convention Centre in Orlando, Florida.

The trade show floor is open from November 17-20 and the expo education conference takes place from November 16-20.

"IAAPA Attractions Expo is the global marketplace for the attractions industry and a must-attend event for industry buyers and decision makers looking for what's new, now, and next to drive their business," said IAAPA president and CEO Paul Noland.

"The trade show floor is massive. In fact, you'll walk more than nine miles of aisles if you want to see all of the great, business-changing innovations featured at this year's expo."
