回复：是我的英语差，还是儿子的理解力差？大家看看这个

I would say it is free for your daughter. Because ticket for 2 and under is free and she is 2.

As my understanding, "2 and under" means 2 and those who are younger than 2.

She would need a ticket if the term is "Under 2".

 

This is kind of confusing. Let's us what other people think. Hehe.
