Orlando's theme parks appeared to have a busy summer. It's a trend all theme parks hope will continue.There are reports some attendance has dropped off.Fewer people are inside Orlando's big three theme parks than compared with the same period two years ago before the pandemic.That's due in part to Disney still capping attendance with reservation requirements, however Universal and SeaWorld are not.Reports for the theme parks' third quarter performances are not out yet but it does appear the summer brought a surge in guests.Ken Storey is the founder of the Orlando Tourism Report. He said pent-up demand from the pandemic drove people back to the parks.“We don't have the exact numbers in yet but I would say based on wait times and things like that we weren't up to 2019 numbers but we were definitely closer to those than 2020,” Storey said.As for the fall, there have been reports that the crowds at Disney and Universal appear to be down with little or no wait times for many popular rides,” Storey said.Storey says the return to school is one factor for the decline but he and other theme park watchers believe the answer is more complex."We aren't going to see that pent-up demand that at the beginning of the year we were talking about. That's pretty much tapered off now,” Storey said.Storey also questions if the rise of the delta variant in Central Florida and the fact that international travel has not come back are keeping the attendance at the theme parks from steady growth.
