I came back from my trip yesterday night, it was awesome.
Anyway if you dont have enough time to travel by roads and u are a budget traveller you can use cheep price airways.
Start from Vietnam I can fly Hanoi - Singapore with Tiger Airways, from Sing it's easily to catch a cheep fly with Jetairasia to Rangoon or Manila. It was shocked me when I see the domestic fly fare in Philippine...
Now back home with 5$ left in my pocket

It's always good to be on the road!!!
