Yes you can take your 11 Year old no problem. For kids it's about $13.00 and $15 for Adults. This past week there was no waiting in line.
Its a great place to take any age. They have many options to choose from and its a fairly large area. It stays crowded, our line was very long and the wait times can be over an hour.
There are two packages to choose from but its $15 dollars for an adult. Well worth the money.
Great spot for kids. We went on my son's birthday so he was free. Total cost for us was around $35, I think. There are multiple options though.
