I don&;t know if you have any plans to stay in different hotels for the first day and the next two days. If so, you can search the chain hotels near Changlong on the first day, such as Seven Days and Hanting, and there are still quite a few, and the price is within 200 yuan. If not, you can choose to stay in the city center, such as chain hotels in front of the park and near Haizhu Square, so it will be more convenient to play around, and you can also take the subway to Changlong without adding too much trouble.
My suggestions for your two days in the city are as follows: D3: Suppose you live near the subway station in front of the park, take Metro Line 1 (direction of Xilang) and get off at Chenjiaci Station, visit Chenjiaci, take Metro Line 1 (direction of Xilang) and take one stop to Changshou Road Station, visit Shangxiajiu, and stop by-scene-spot/mafengwo/10088.html restaurant or Taotaoju for dinner. After eating, take the subway line 6 (direction of Changba) for three stops to Haizhu Square. If you have time and interest, you can go to the Sacred Heart Stone Room Church in the province to take a night view, otherwise you can directly transfer to the subway line 2 (direction of Jiahe Wanggang) for one stop to gongyuanqian station and return to the hotel.
D4: Take Metro Line 2 (in the direction of Guangzhou South Railway Station) in gongyuanqian station, then change to Station 2 of Metro Line 8 (in the direction of Wanshengwei) at Changgang Station, get off at Zhongda Station and visit Sun Yat-sen University. In the afternoon, take Station 2 of Metro Line 8 (in the direction of Wanshengwei) to Kecun Station, then change to Station 2 of Metro Line 3 (in the direction of Tianhe Passenger Station) and get off at Zhujiang New Town Station, and visit flower city square, with Grand Theatre and Guangzhou Library along the way, overlooking Guang Zhouta. After that, you can take the subway APM line, get on the bus at Huacheng Avenue or Grand Theatre Station, climb the tower in Guang Zhouta, watch the sunset, and then watch the night view of Guangzhou. Take the subway back to the hotel after watching it.
Another advantage of living near gongyuanqian station is that if you also go to Guangzhou South Railway Station on your return trip, you can get there directly by subway line 2, and you don&;t need to transfer, so if you take your luggage.
