We are looking at doing this loop and want some suggestions as we have never been there.
We have about 1 week in total and were looking at flying in Udon and driving straight to Nong Khai stay 2-3 nights then drive to Loei for 3-4 nights and back to Udon for the last night.
1 We aren't sure whether we should stay o/n in some of the smaller villages/town outside these places or not.
2 We don't know whether we should prebook a car online or just turn up at the airport. If it's the same price and there's plenty of cars we would prefer the later.
3 Any side trips from these places would be good.
4 We are going June/July which is rainy season but we've never had any probs with weather that time of year before but we have never been to this area before so advice on that would be good
