Mrs G-ARVE and I are planning a train trip from KL to BKK, taking a week or so to get from one to the other. One way as we'll be flying back. Am looking to offload some of my 500k or so HH points along the way. Would really appreciate some advice of where we ought to stop off, and for how long. If there is a 'must see' place that does not have a Hilton, would consider that too.

If its at all relevant, am HHD.

Thanks in anticipation.
