d or g train

Thank you for the info on the K-train. Since I am flying in so late and hope to find a hotel which generally you have to check in after 2 pm at most of them, I am hoping I will be able to stay at one very close by, then it will be easy for me to take the earliest train from the train station (at the south side I think) to Zibo. Would like to find the lowest price of getting there. But would take the g or d train.
