After about 2 hours we finally mustered the willpower to reload ourselves with our luggage and begin the 15 minute walk to the city centre, but we got totally lost and ended up in the suburbs. We asked for directions toward the city centre and found that no one spoke any English out here, but the lady we asked found us someone who knew a few words. 

This guy then tried to get me and Dave and our bags onto his motorbike, and tried to persuade us to put our faith in him by saying "trust me, I'm a policeman". Aye sure you are pal. We walked off back towards the ruins to find a tuk tuk and went back to the centre, where we spent the next 5 or 6 hours in a bar getting steadily drunk with a Dutch family. At 23.30 we dragged ourselves over the road to the train station, boarded our train and promptly passed out.
