Dear Steven, 

I’m glad to hear from you again. I am also pleased to hear that you’ve got a ten-day holiday and are coming here to have a visit in the Disneyland.

In order for you to save some money, I’d like to give you some tips. I suggest you buy the five-day all –in-one hopper pass, which is HK$1,460 for visitors aged 10 to up and HK$ 1,200 for kids aged 3~9. You can save money compared with the tickets you buy separately. I think you’d better have lunch at nearby restaurants, where excellent food is served and the service is good, but you must make a reservation before leaving home. You will be a Gold Card member if you pay HK$520. With the card you can save 20 percent of money for hotel rooms. My last tip is that you’d better not buy any souvenirs until the end of your journey. I spent a lot of money on expensive but valueless things.

Enjoy your trip and all the best wishes!

Yours,

Mike
