Imagine that you have returned from your language study trip. You have a lot to tell your friends! So tell them what you did, what you saw, and how you had prepared before leaving.
If you did go it depends on what you did, what you saw, and where’d you planned to go. That would answer, what you did, what you saw, and how you had prepared before leaving, also depends on what you had planned to do and see. (Even if it’s fictional.)
If you’re answering back in French, this is what I would say,
Mon voyage était génial! Je suis allé voir la Tour Eiffel, je suis allé dans les zones traditionnelles et j'ai mangé des plats traditionnels! Avant de partir, j'ai préparé une caméra et une carte de France.
