I stay occassionally at the Jianguo Hotel. It is a very comfortable, well-located 4 star hotel. I have no complaints about the room or the breakfast. However yet again I was let down by the lack of local knowledge by the desk clerks. I wish they would admit to lack of knowledge!
Due to a delayed flight I had to stay the night in GZ unexpectedly and needed to get to Zhuhai veyr early the next morning. The desk clerks were not busy when I checked in a midnight so I asked if they could look up bus departure times. Without looking they said the first bus is 8:30 am. Since this was too late for me I arrived at the bus station at 7:45 - to find the 7:50 bus to Zhuhai was just boarding, but I was too late for a seat.
