I am currently in Bangkok where the weather is boiling hot, the locals are in fine fettle and the place is buzzing with superb business opportunities.
Unfortunately, VK asks a very valid question as the place can turn in a very short period of time as I experienced during last years riots.
I plan to be back in July, however, if there is any sign of trouble I follow the advise on the Governement websites as well as speaking to local contacts in the region.
I am still booking trips over here and I gerenally work 2 to 3 trips in advance.
The one point people should bear in mind is that Thailand relies very much on tourism and whilst the people may revolt the majority do not want the country to suffer the economic effects of tourists and business people staying away.
