I have a plan to backpacking to Thailand next January or next summer, please tell me how much money I need for low budget traveling?and please tell me good restaurant/places to eat and also good hostel/cheap hotel

thanks

my choices are Thailand,India,Korea and China.

I am particularly interested in getting leads in Cambodia, Myanmar, China, India, Laos, Thailand, and Vietnam. I am interested in all kinds of beads.

Im 21 and me and a couple of my friends are trying to plan a trip to southeast asia, like thailand, vietnam, ect. Were looking for fun cool places with young hip people and places to party but also to do some site seeing and to learn about the culture during the day. Also would like to hear about the best beaches to visit and any other travel information like best hotels, airports, bars.
