lol.
Ok, for starters, what stimulus text are you doing?
Secondly, a basic concept of journey needs to be applied to that stimulus text. Look at how the protagonist or responder changes, for example (if they do). Or perhaps the responder "goes on a journey".
Thirdly (although most importantly) what type of Journey are you doing? Physical, Imaginary, or Inner?
My advice is really just to brainstorm as much as you can. To make it better, start looking at how the journey is represented - techniques etc. I'd be more than happy to look over and critique any drafts you do - just pm them and your email addy to me
