Democratic Alliance against Dictatorship DAAD is doing a counter rally against PAD. DAAD is a supporter of the current government PPP (People Power Party) and PPP is a proxy government for TRT (Thai love Thai).
The PM and leader of PPP Samak is telling Thailand he is staying put and will not resign even if most of the military does not support him.
The rail way and two airports in South Thailand Phuket and Krabi is still shut down and tourists are stranded. Most of them are going for busses back to Bangkok.
If you planning a holiday in Thailand then go to something like Hua Hin, Pattaya or something reachable by buss. Even if trouble will erupt in the Capital nothing will even happen in Hua Hin since the His Majesty the King is there.
