I will be in Hong kong with my family for 7 days in Dec 2013. What are the places that you rommend for us to visits ?

If you have childern with you, the Disneyland and the Ocean Park are necessary to go. If no childern, I think you can pick up one from them.
Besides, the Repulse Bay, the Peak, the Ngong Ping 360 & Ngong Ping Town, the Causeway Bay, the Victorial Bay, the Temple Street, Ladies Market, the Harbour City are suggested to go.
If you want to taste the good food, the Causeway Bay area is suggested.
