Direct bus to Panyu, how long does it take & what are the attractions in Panyu? Easy to walk around?

You can go to the local Gongbei Bus Station or Doumen Bus Station to take a direct bus to reach Panyu.
As for the attractions, Chimelong Holiday Resort and Xiangjiang Safari Park are suggested. Both of them are at Panyu, but whether they are within walking distance depends on your staying location.

Staying at Paradise Hill Hotel in Zhuhai. Thought of going to visit Panyu. How long is the bus journey & when is the last bus back to Zhuhai?

Oh, I see. Your hotel is only 5-6km away from Gongbei Bus Station, so you can certainly go and take a bus to Panyu there. It will take about 2.5h to Panyu.
You will reach Panyu Qifu Xicun. Then you can take bus no. 10a to Hanxi Chimelong MTR Station and then start your trip in Panyu.
The last three buses back to ZH Gongbei depart from Panyu Bus Station at 17:40, 19:25 and 21:00.
