I have to agree with what the other BKK-based posters have been saying. While there are definitely some inconveniences associated with the current situation (e.g. - I couldn't use the skywalk near Chit Lom and Central World for about an hour this weekend due to a flash protest), I have never felt unsafe or uncomfortable in central BKK (where I live and work). For those looking at vacations in Koh Samui, Phuket, Krabi, Hua Hin, etc - all reports I have heard say that things are operating as normal, with no military presence observed. Here in Bangkok - the big tourist attractions like Wat Phra Kaew (Emerald Buddha) and Wat Pho (Reclining Buddha) are still operating as normal.

Also - a quick story from a friend of mine who just got back from Chiang Mai. He and his girlfriend took a taxi from a guest house near the eastern gate to the Chiang Mai airport early in the morning (4am), during curfew. As they approached the only military checkpoint on their way to the airport, the driver quickly turned on the dome light in the taxi, to show that the occupants were farang/western european. The checkpoint officials casually waived along the taxi; the driver did not even need to slow down that much.

I am sharing above, just to give others an idea of how tourists/foreigners are being treated during the current situation. It seems to me that the military does not want to scare away foreigners/tourists, and as long as one stays away from protest areas/rallies - one should be fine. If things start heating up and getting to May 2010 levels, that will be a different story...but things right now are "relatively" normal.
