Want to go to Hong Kong and Macao to travel freely, who can help give a specific strategy? It's better to be economical!

Day 1: Wong Tai Sin in the morning, Ocean Park in the afternoon, Victoria Harbour (there is Bauhinia Square on the shore of Victoria Harbour) in the evening, and then you can go shopping in Causeway Bay or Mong Kok. Accommodation in Sham Shui Po is relatively cheap (HK$ 200, legal hotel, air-conditioned and comfortable).

The next day: Avenue of Stars (Toys R Us and Harbour City are on the avenue), and take the cable car to Taiping Mountain in the afternoon (it seems to be around 15 yuan, which is super convenient anyway).

Never go to Disneyland. Ocean Park is not fun enough, but it has been queued for a long time.

Next stop: Macau: In the morning, go to Sao Paulo Archway (a historic city in Macau) (there are many churches and supermarkets near the archway), in the afternoon, go for a walk in several large casinos such as Portugal, Emperor and Jinsha (several casinos are very close, so it is recommended to walk), and in the evening, go surfing on the beach around the ring road.

Those casinos can take a free casino through train at Guanzha, Hengqin or the pier.
