My family is visiting Hong Kong this coming October 27 to October 30.

1. About the weather, the previous statistics show that it was 75 F to 85 F. It will be hot. Summer clothes are enough.
2. What's your budget of your accommodation? In general, Nathan Road Area is a popular area that has many cheap but nice hotels. You can go to Silka Seaview Hotel. The price is 300 to 350 HKD per night. The surrounding transportation is convenient. It's located at 268 Shanghai Street, Yau Ma Tei, Kowloon. Hope you like.
3. To be honest, it's not necessary for you to hire a tour guide or join in a tour group. As HK is an international metropolis with modern transportations to be easily accessed, and also English is widely used, so it is quite convenient to find the way to your destinations.
