What is the annual event that occurs each December at Walt Disney World?

The annual event that takes place each December at Walt Disney World is the Epcot International Festival of the Holidays. This festival showcases holiday traditions from around the world and features the Candlelight Processional, live performances, and special seasonal food and beverage offerings at various Global Marketplaces throughout Epcot. The festival celebrates cultural diversity through holiday storytelling and entertainment, making it a cherished experience for guests wanting to engage with various festive traditions.

While Magic Kingdom does feature special holiday decorations and events, it does not hold an officially named event called "Magic Kingdom Winter Wonderland." The Disney Festival of Lights is not a recognized standard event in the Disney Parks' calendar, and the Epcot Food and Wine Festival, while popular, occurs in the fall months and concludes before December. Therefore, the Epcot International Festival of the Holidays specifically highlights the December celebrations at Walt Disney World, making it the correct answer.
