Hi Ian, Nakhon Sawan is as interesting as Novosibirsk in deep siberian winter; try to make it down to Lopburi, recommended Hotel: "Lopburi Inn Resort" (not the Lopburi Inn which is a fleabox) its a little outside of town in direction of Saraburi. Nakorn Sawan-Chainat-Singburi turn left to the 331 to Lopburi. After overnight stay continue from Lopburi to Saraburi, about 10 kilometers from Saraburi turn left to Nakhon Nayok route #33 down to Prachinburi, follow this road until you come either onto the 304 which southward merges with the 331. Carry on on the 331 until you meet the 36 that means Bkk-Rayong highway, and just follow the last kilometers to Pattaya. With this you avoid Bangkok, any tollways the motorway on which you cannot drive anyway. The 331 is 4 lanes (2+2) with little traffic and next to no police, if you drive via Kabinburi there's sometimes some guys in brown with real radar ! More interesting is the small road via Si Mahaphot, sorry I don't have the roadnumber because have driven this one for many times and remember by sight. If you choose this road, please email or call me as I'm living on the 331 at the area where they just expand it to 4 lanes, place called Bowin, if the timing is ok I will join you from there or even go up a little on the 331. Least you can get some refreshements at my house. Looking forward to see you again, cheers Franz
