Do I have to pay for amusement park to get in to play mini golf go carts and arcade games? And are the gift shops and snacks in the zoo part

You can use the games and shops without admission fee o believe you're only exempt from rides .

I haven't been in the amusement park but I've been in the zoo part and the zoo part has food as well as gift shops. I think you do have to pay to get in the amusement park as well as the zoo but it's not that expensive.

There is no charge to walk around the amusement park so yes you can play mini golf, go on go karts, and in arcade and one of the gift shops without an entrance charge
