Officials at Walt Disney World in Florida have apologised after its ticketing system crashed on Monday leaving guests waiting in queues to get into the park for hours.

The barcode scanner technology was reportedly back up and running again by Monday afternoon, with Disney World apologising for the inconvenience to visitors.

The park’s officials said there had been an “interruption in its ticketing system.”

Fans took to Twitter to express their frustration with the issue, with one fan stating: “Two-and-a-half hours in line at guest services (and counting) in blistering heat. At least we got free water.”

Another added: “The barcode scanner system at #WaltDisneyWorld Magic Kingdom stopped working this AM. Apparently only people with MagicBands could get in. Wow. Horrible UX and CX.”

On any given day, the Magic Kingdom can host up to 50,000 visitors and up to 20 million each year.
