Six Flags adds Renaissance weekends in March VALLEJO — Six Flags Discovery Kingdom, in partnership with LAVA Productions and The Northern California Renaissance Faire, announced a new whimsical event – Renaissance Days. A limited-time addition to the park’s popular Marine World Experience, Renaissance Days will transport guests back to the Renaissance Era as they encounter wondrous characters in colorful costumes, hearty food, period shops and fanciful décor in a safe and fun environment. Six Flags worked in partnership with its health and epidemiologist consultants to create an enjoyable visit that meets or exceeds federal, state and local guidelines for sanitization, hygiene and social distancing protocols.
