Kennywood, Idlewild, and Sandcastle have been named in a class action settlement.

If you visited the parks between Dec. 4, 2006 and Dec. 20, 2011 and used a debit or credit card, you may be eligible for free admission.

The settlement resolves a lawsuit over whether Palace Entertainment, the company that owns the parks, violated a law by printing too much card information on admission receipts.
