Generally speaking, yes. Using common sense means you'll probably get out of Thailand in one piece. Violent crime against foreigners occasionally takes place, but overall it's safe and women in particular find they feel more secure than in the west. The biggest problems are petty theft, scams and traffic accidents.
Some sensible actions to take:
1) Wear helmets when riding motorcycles or bikes
2) Don't stray into higher crime areas
3) Don't get drunk and pick fights with bar staff
4) Don't travel on the roads during the Thai new year break, Songkran, in April.
Regarding the ongoing protests and closure of Bangkok's international airports in later November 2008, while Thailand remains safe, if has become far more difficult to get in and out of. While the airports remain closed, the best option is for travellers to either make their way out of the country overland, or to head to one of the southern airports which offer international flights allowing one to reach regional hubs like Singapore and Kuala Lumpur.
The airport closures have been caused by the People's Alliance for Democracy (PAD) -- an anti-government group -- that has been campaigning for the current administration to stand down. The airport closures are just the latest step in their escalating campaign. The long-festering dispute has left Thai society polarised, with very strong, bordering on irrational, emotions felt on all sides. Matters have been further complicated by the government appearing to have lost control of the Thai Army (who have also called for the government to stand down).
For now, outside of the gross inconvenience of having the international airports closed, Thailand remains safe to travel in. However, we'd say the situation is fluid and changing rapidly -- and you'd be well advised to keep a close eye on news developments coming out of the Kingdom.
