Itinerary is finalised now. Have been busy this week getting all the flights organised. With only 50 days to go before we leave, got to admit this is a strange trip this year, what with the Icelandic ash cloud possibly going to return before we leave then with Bangkok in turmoil.
For the moment, we are booked to fly in to BKK and stay overnight in downtown. but might eventually decide to stay out at the airport if things deteriorate.
For the rest got all the flights booked for Thailand, Vietnam and Cambodia and Laos (I already had Burma) and am now getting places to stay lined up where it is necessary.
