Read this thread from the general forum form a few weeks ago. Lots of good stuff in there.
backpacking/pokering through Europe
good luck on your journey.
I highly recommend taking way more money than you think you will need.
Also consider that you probably won't want to be spending THAT much time on a computer grinding out the hands when you could be seeing the world.
Note that the poster in that thread reported only about 10 hours per week.
So why not play enough NOW to mostly fund the trip...and then just keep up the momentum of playing through as much of the trip as you can?
That way you might not be stuck eating and lodging super-cheap and miserably through too much of your journey.
