From wdwig.com:
"The Boardwalk offers a wide range of activities that differs from day to day. Seasonally, you will find midway games, jugglers, entertainers, hand wax molds, food vendors, magic shows. Bike riding along the Boardwalk is a popular past time. At night, the night clubs and restaurants spring to life and bring with them music, laughter, and people.
One of the favorite activities for families and groups are renting the Surrey Bikes. You can pedal your way around Crescent Lake , over to the Beach/Yacht Club , Swan/Dolphin. Surrey bikes are no longer allowed on the walkway to Epcot's World Showcase. Rentals are available on the Boardwalk itself."
We've always found different entertainment each night we visit, but it's always first class and a great time!
