First look at what's new in Walt Disney World

Major updates are coming to all four Walt Disney World parks! In Animal Kingdom, Rafiki’s Planet Watch is being transformed into a Bluey experience, set to open this summer. Over at Epcot, the patriotic Soarin’ Across America debuts by Memorial Day for the nation’s 250th birthday. Changes are also hitting Hollywood Studios, where Rock 'n' Roller Coaster closes March 1 to make way for a Muppets takeover. Meanwhile, Magic Kingdom fans can look forward to the return of Big Thunder Mountain and Buzz Lightyear, both reopening this spring after major refurbishments.
