Swim in Luna Park pool. Walk over to the Beach Club and get a milk shake at Beaches & Cream. Pick up a Krispy Kreme at the Boardwalk Bakery for breakfast. Stand on the bridge by the international gateway outside Epcot and see the fireworks. Watch the buskers and musicians on the boardwalk at night. Mini golf at Fantasia Gardens as you already have planned is fun. Cirque du Soleil show at downtown Disney is wonderful, not to be missed.
We hardly ever go into the parks.
