My plan is to fly into Guangzhou baiyun airport, stay in Guangzhou for 2 days, after which I plan to visit Macau for 1 day via Zhuhai Gongbei land border, then onto Hong Kong disneyland for 1 day via the bridge, and then via the train from HK Kowloon West to Guangzhou. Finally I will spend 1 last day in Guangzhou before leaving to another country. I am from New Zealand and qualify for 15 day visa free.
