文法有錯嗎？

Recommend a Wonderful Jounery For You

文法 seems to be okay. But by common sense, if you still haven't completed, i think it is not a journey (my journey to the US last year is wonderful)......I think this one would better:

Recommend a wonderful route/detour for you

Firstly, you spell journey wrong..
and you don't recommend a journey.
Either you recommend people to go somewhere. Or you can use something else instead.Just like, you can recommend a book .
At last, you don't recommend something "for" you, you recommend something "to".
