Travelling in Thailand is pretty safe if you do not try to do something weird, like walking alone in the dark or go to every pubs , get drunk with strangers or even stay up late at night by the beach alone. There are rules for traveler, the same as in many countries, like do carry valuable stuff by yourself at all time and do not leave them in the bag or baggage. I once lost my baggage in Rome, it was out of my sight only 1 minute. Got lost in Paris, no one gave a damn because they do not speak English.  So anything could happen in any countries if you are not cautious enough.

Thailandnights Tips
Plane : Traffic in Bangkok is mostly very busy specially rush hour 7.00-8.00 am and 5.00-6.00 pm. working days.  At the weekend the traffic start busy at around 10.00 am until 8.00 pm. and mostly busy near department stores, Thai people go out a lot and the car parks are mostly full.  So prepare 1 hour extra for flying domestic and 2 hours extra for flying oversea. The planes are mostly the same, if you are interested in low cost flights, consider Air Asia and Nok air. The flight tickets are cheaper about 50% compare to regular prices. They cut down some services like food and drinks, just flying alone. Also it is very cheap if you book the flight online in advance about 1 month, you will be surprised with the lowest fee.

Train : Cheaper and  more safe but slow.  If you are not so rush and would like to be closed to local people, this could be the choice. All destinations are in big cities and tourist places. Look out for the time and be there on time, if you stay in Bangkok prepare 30 minutes extra for the traffic.

Bus :  Thai people call “Bus” because they are buses, like a school bus in the movie or the Greyhound in USA and the European may call them “Coach” which I find them quite different in terms of quality and service.  Most buses are not so clean because they have been using everyday and they may not have time to do it properly. The good things are cheap, fast, have all routes you want to go and available mostly around the clock. Do sit around the middle rows, those front seats are not recommended.

Rental Cars : Driving a car in Thailand is not so easy. The roads are good enough, some routes may under construction, you have ask local people before leaving  the town. The most caution is the small roads where all directiods share the path.  Accident in Thailand is in high rate. Drive slow, not over 100 km/hr could safe your life.
