請教，訂Uffizi ticket -- 先謝了！

在Uffizi網站，information這樣說:

Tickets: 

Full Price Reduced Price: European Union citizens aged 18 to 25 European Union teachers 

Free tickets: Children under 18 years old from any country Children under 12 (must be accompanied by an adult).

但訂的時候隻有這三個選擇：

 

Number of tickets Full price

 

Number of tickets Number of tickets 

European citizens from 18 to 25 years *

 

Number of tickets Free

European citizens under 18 or over 65 years old **

 

 

１８歲以下free隻對European citizens嗎？Information裏說Children under 18 years old from any country.
非European union的小孩有免費票嗎？
