Has anyone been travelling around Asia before? If so.. what route did you take? How long did you go for? And how much money is needed for around 3 months?
Amazing Grace :-)
Yes, TA members have travelled around Asia. That's why we're here in the forums.
Your post is far too vague to get helpful replies. Go to Travelfish.org for some in-depth research to find which places are likely to suit your preferences and interests.
How much money to take? Might as well ask "how long is a piece of string"? We all have varying spending habits, so spend differing amounts. Best thing to do is to take a wad of cash along with at least two debit/credit cards for top-ups.
Definitely people have gone before and written books about it. You could try https://shop.lonelyplanet.com/products/south… or https:/… . The local library would be likely to have still useful editions available.
If you hate spending any money on research you can start with https://www.travelfish.org/trip_planner
You take what route suits you, you can go to a variety of different countries via as many different permutations of routes.
So, as they say in Thailand 'up to you'
