March 4 is going to be a busy day! If you’ll be at Walt Disney World on March 4, don’t be surprised if the crowds are heavier than normal. Not only is it the first day of Mickey & Minnie’s Runaway Railway, it is also the start of the Epcot International Flower & Garden Festival. If you’re going to be here and want to avoid crowds, you might want to visit one of the other two parks.
