Hi I would like to visit taiwan from 19-25 /12/2014 with my family of 5.

You can download the app of tripadvisor to you smartphone. It will show you where are the shoppings, attractions to visit. Follow the advices given you will have a great time. You only just type in the city you want.

No, it is not typhoon season in Dec. Actually, the typhoon season is usually from June to Sep. sometimes till Oct.

At that time, I suggest you have fun at Disneyland Resort, Ocean Park and the peak. Also Tsim Sha Tsui/Avenue of Stars, Stanley Market and Aberdeen are worth your time.

Think you confuse Hong Kong and Taiwan.

Yeah, I agree. But Ms. Winster was right with the weather description. For the attractions, I recommend Ali Mountain and Sun Moon Lake most!
