Thank you for the quick responses. Even though I am considering last week of Nov, I do have flexibility on the timing. I understand availability is what matters at the end, but trying to go for the best product with in those available options. We have been to Tokyo before so maximizing the options. Is there a direct flight to/from Koh Samui from international destinations? I may want to look into flying there or getting out of there directly rather than going back to BKK to get out. We are looking at BKK, Koh Samui and Angkor Wat as the three locations for a 10 day trip.
