假设你是李华，寒假期间你准备和家人去香港迪斯尼乐园游玩。你想了解有关订票方面的具体情况，例如：可否在网上订票？团体购票是否可以打折？可否因故取消订票？你在互联网上查到了一份门票价格表，但还有些具体信息不明确。请给迪斯尼乐园发一封信，询问有关情况。

参考范文

Dear Sir / Madam

     My family are planning a visit to Hong Kong Disneyland this winter vacation. I’ve got some information about the ticket prices on the Internet and now I’m writing for some detailed information.

     I wonder whether children under 3 need to pay for a ticket and what is the difference between a peak day ticket and a special day ticket. Is it possible for us to get a discount if we buy tickets as a group? Can we book tickets through the Internet? Besides, I’d like to know if we are allowed to cancel our ticket bookings if we cannot make the trip for personal reasons.
I am looking forward to your reply

Yours,
Li Hua
