Is it possible to visit both Phimai and Phanom Rung in one day mainly by public bus or train? I plan to arrive in Nang Rong the night before, stay in a guesthouse, then wake up early to visit Phanom Rung at sunrise then Mueang Tam by motorcycle taxi organised by the guest house. I figure I should be finished before noon then want to head to Phimai. Assuming I could leave Nang Rong around noon, take a bus to Khorat then transfer to a bus bus to Phimai, is it realistic to think I could get to Phimai by 5 so I would have time to get to the temple by sunset? I would be then spending the night in Phimai. Do I have to go back to Khorat from Nang Rong (or Buriram) then take a bus to Phimai or is there another way?
I know there are private tours that will take you to see both in a day but they are well out of my price range as I will be on my own. I'm just wondering if this is at all feasible or if I shouldn't rush it and travel to Phimai the following day
