We just got back from Sukhothai at about 1815 yesterday. we took the pick up, up one day sight see the next and return. That would have been far to difficult for me on the bike. I tried it both ways the GPS fastest route took us to Khan Kean boring as hell, HWY 12 did pick up some nice curves ext. before Phittslanuk, boring here after, We left at 1000 Hrs arrived 1830. Distance from home 523 klms. Spent a few hours checking out Sukhothai Historical Park Not bad wife 50 baht me 100 baht. My wife mentioned the people were not to friendly. But, there were loads of tourists from all over the world. We sit out for home around 1230 Hours, keep in mind I pushed hard on both trips top speed of 140 and a average 79 Klms per hour. Arrived at home 1815 hours this was on the shortest distance of 455 klms. Easy one day ride, the difference if I was on the bike I would have had to stay that night and rest up the back and I would have taken a straight shot back home. It was funny using thee shortest distance we ended back on 2216 2013 and 203. The only real tough part is 12 with trucks and mountains hard to pass. same with 203 until you hit the four lanes. I hate dodgy passing but if you want to finish in open day you will be doing some. Actually with type of activity I would rather be on the bike it's smaller so easier to tuck it into places. Some of the passing you might actually need to pass nine vehicles rare that you can that at once. So you pick up what you can safely and works around them till you are in the lead. Curves I was going just as fast as would have on the bike, wife and I both agreed felt safer on the bike. Just a lot easier to control. Sukhothai was great the park is in the old City. We stayed at Le Charme Resort 850 a night but a real class act (055-833333) 1.4 klms from, the park. Nice pool free breakfast with eggs liked fresh. The restaurant had both European and Thai food and it was good. There are a lot cheaper places all around to include the Old City Guesthouse 450 baht and walking distance to the park. Restaurant 100 meter away with foreign and Thai food. We don't this a lot so staying in a nice resort is really a treat for us.. Sukhothai is certainly worth seeing once. I would suggest searching the internet for history. We have a ton of photos down loaded already, next I will try to figure out how to post them.
