Would it be difficult to travel from guangdong to zhangjiajie national park?

As I know, there are several flights from Guangzhou Baiyun Airport to Zhangjiajie every day and you are recommended to take the one departs at around 11:30. After 1.5 hours' flight, you will land in Zhangjiajie. Upon arrival, you can take a taxi to Zhangjiajie Bus Station first and then get on a bus there to the scenic area.
