There's a very good article in the Observer today by Bill Condie rounding up much of the recent history and current political situation in Thailand - a great read if you want to understand the crisis better.

Many people have asked us if it is still safe to travel to Thailand. So far the main protests have been focused on Bangkok and tourists have never been targetted, indeed apart from those stranded in the airport many travellers have gone on to enjoy their holidays.

Indeed due to the sudden drop in arrivals from within Asia (it seems the protests have done less to deter Europeans and Australians than visitors from China, Japan and Korea) some great deals can be had on accommodation - plus since so many people rely on tourism for their income in Thailand you will be helping to support Thai people by visiting and spending money in their restaurants, bars and hotels.

Yet it does pay to inform youself to the latest news from the area - checking Thai newspapers like the Bangkok Post is a good start - though bear in mind the press is not completely free in Thailand. You could also read the views of local bloggers like Bangkok Pundit, or check other papers from the region such as the Straits Times from Singapore. As ever you should also read the FCO's advice from the Know Before You Go website - this will cover health advice as well as updates on the political situation.
