Shamu's Express is Sea World Orlando's first family-oriented roller coaster. Located in Shamu's Happy Harbor area of the park, the coaster has killer whale cars traveling at speeds of up to 28 mph along more than 800 feet of track. Two more family-friendly attractions include a jellyfish-themed samba tower ride and a waterspout-themed teacup ride. "Jazzy Jellies" lifts and spins families in jellyfishlike seats, while "Swishy Fishies" enables adventurous youngsters to sit in oversized seats while spinning around a giant waterspout. -- Georgina Cruz, Special to the Sun Sentinel FYI: Sea World is located at the intersection of I-4 and the Beeline Expressway, 10 minutes south of downtown Orlando.
