According to a university teacher named Bill Zanetti who studies this sort of thing, the highly anticipated opening day for Star Wars Galaxy’s Edge in Disneyland (set for sometime during the summer of next year) could see 200,000 fans lining up to eagerly experience the new Star Wars theme park attraction. We all know Galaxy’s Edge is going to bring in scores of fans right from the jump, but attendance numbers like this could cause serious problems for Disneyland and result in extremely long, patience-testing lines/queues.

Up to 200,000 people could descend on Disneyland for opening day of Star Wars: Galaxy’s Edge in Summer 2019. This could overwhelm the Anaheim theme park with 10-hour lines, swamping parking and traffic in the area.

That’s the astonishing prediction from theme park experts. They expect Star Wars: Galaxy’s Edge to be one of the biggest grand openings in industry history.

Bill Zanetti is an Orlando, Florida university teacher who studies theme park design, operations and management. He expects 200,000 people to line up to be the first inside the new themed land.

“The number is based on what I believe is the actual interest,” said Zanetti, who teaches theme park courses at the University of Central Florida. “That’s just how many people I expect to descend on the resort on the first opening day.”

Galaxy’s Edge in Walt Disney World will be opening to the public sometime in Fall of 2019.
