The citizens of Main Street, U.S.A. in Magic Kingdom park are bursting with excitement now that spring is in the air. Dressed to the nines in bright pastels and with a few new songs in their hearts, they arrive in town on a horse-drawn trolley adorned with colorful bouquets of flowers and ribbons. Put a little spring in your step and join in the celebration—another part of Limited Time Magic at Walt Disney World Resort.
