Orlando is the most popular destination for families during spring break-- so it's fortunate indeed that dates for spring break vary in different parts of the US and Canada. Just imagine what line-ups would be like at Disney World, if every school, everywhere, closed its doors the same week!
Typically, "spring break" means ten days off school, in mid-March to mid-April.
In addition to all the usual Top Things to Do in Orlando, the spring break weeks bring some extras:
At Disney World, the Epcot theme park has its annual Epcot Flower and Garden Festival, with many amusing topiary figures of Disney characters (a signature feature,) programs for grown-up and kid gardeners, and free outdoor Flower Power concerts. The Festival has a long run, from mid-March through May.
