if i purchase a ticket with my union discount can i still take a child in for free on the month of october

That is what it says on the promo: buy a ticket for one adult, you get a free kid's entry

I believe as long as your ticket specifies it's a "Kids go free" ticket it should be fine. I would call to confirm.

I know for Military Discount we still had to pay for the child unless they were under 2

Saturdays in October are brick or treat blackout days for annual pass holders. I would call and confirm if you plan on going on a Saturday.

I think so
