Can you have a kids party here?

Yes

I believe you can

Yes! I did my son's 1st birthday party at storyland and it was $50 to reserve the area of the park and it was $200 all together. It includes free train ride passes for all guests and a storyland key and the birthday girl/boy gets a children's book! They help clean up and set up too and they supply cups, plates, utensils, etc.

Yes. Theres like 3 areas. You can even have a party in the Castle in StoryLand
