"All our parks delivered strong performances for the year," said Matt Ouimet, Cedar Fair president and CEO. He said Dorney was among the parks "leading the way."

Cedar Fair reported full-year net revenue of $1.07 billion, up 3.9 percent over 2011. Net income was $101.2 million, or $1.81 per diluted limited partner unit, up $30.5 million from 2011.

"Our new e-commerce system and improved consumer messaging led to record season pass sales, while premium benefit offerings, such as Fast Lane, contributed nicely to the record in-park guest spend in 2012," Ouimet said. "A strong capital plan is also important to the growth of our business, and we believe our 2012 capital strategy was a success."

He said he has confidence in the 2013 season.

"Going forward, we will continue to strategically invest capital across all of our properties, particularly where we believe we will achieve the greatest return on investment," said Ouimet.
