P’Noom,
Now I have flight schedule of Ajindar and Nitin they are in the same flight on 13 September 2015 arrival BKK 13.45 PM
On 13 September 2015 we will leave from BKK to Chainat at 3.00 PM. That means do not booking room at Novotel .
I’m not sure about flight schedule of other participants, they would like to stay on 12 September or not
If somebody stay at Novotel on 12 Sep 2015 I will make appointment at Novotel Suvanabhumi.
