Due to the global pandemic, Disneyland Paris (like all of the other Disney theme parks around the world) shut down earlier this year, but then reopened in July. Eventually, however, COVID-19 numbers in France began increasing again, and the country went into lockdown, forcing Disneyland Paris to close temporarily once again at the end of October.
Disneyland Paris was set to reopen on from December 19th through January 3rd, but it seems recent regulations set by the French government have caused plans at this theme park to change.
