Tickets at the gate are $32/adult, $17/kid (kids are free on sundw, age 5-12), children under 5 are free every day. You can buy tickets online for $25/adult and $13/kid. If you plan to go next year, sign up for the email mailing list off the website. They have multiple sales leading up to opening weekend.
Depends on the age. Some kids get in free. I would recommend you get tickets at a Walgreen or Woodforest before hand (discounted). With tax on their website is ~$27 per ticket
