Hongkong is very easy to DIY. You don't have to join group tours. :)
For Macau, we initially planned for a DIY trip. However, just right outside the pier, a fellow Filipina approached us and offered us to be our tour guide. The best thing is she only charged us a small fee. So we grabbed her offer without thinking twice. Haha.
For Shenzhen, we have no choice but to join a group tour. The tour is quite expensive for a budget traveler like me. .
I will discuss the details of this trip in my next blog.
Thanks. ;)
