It was first solo international trip to Bangkok it is one of the best international destinations to start . Travelling in Bangkok is very easy using local Bus/Trains will save lot of money. For best view of city must use BTS (sky trains). As a lone traveller I choosed to stay in hostel (Retz Bangkok@ sukhumuvit road 22. Very near to many places like BTS and super markets and dinosaur planet and a beautiful park and many more..it will be centre of city..
