Once a year on the first Saturday of Frebruary is Museum Day. All museums are free and the Zoo and Fairytale town are 1/2 price
Sadly....., I've know idea as to any special days! Going on they'r website may be your best course of action.
They do have discount days. Their website lists them on the events page i believe.
They do have promotional days. I would go to the website to see when they are
Last Saturday was half off day but im not too sure how often they do that there
Holidays are discounted, like Thanksgiving and Christmas Eve, but i don't think there are any free entry days.
