Disney has created a Disney World UK website just for us Brits, but that means that your saved password might not work properly.
If you're wondering why your device's built in password manager isn't working on Disney's site, it's because they appear to have changed the URL structure of their website for UK guests. This means you'll have to login again to save it on the new URL.
Before, the URL structure would be something like this: https://disneyworld.disney.go.com/en_GB/entertainment/disney-springs/cirque-du-soleil/
And now, it will redirect you to the new primary domain of disneyworld.co.uk, for example: https://www.disneyworld.co.uk/entertainment/disney-springs/cirque-du-soleil/
Going to mydisneyexperience.com will redirect you to disneyworld.co.uk/plan/
It's unclear why Disney has made this change, it could be to get us Brits off the American version of the site, or it could be due to easier GDPR compliance.
