First, you need to go over to the Cruise Trip Report thread. There is no set format. I start mine from the beginning with a little intro about the trip and then go from there in chronological order. I love to see lots of pictures in trip reports so I add many in mine. However, I don't add a lot of personal family pictures, just places I see. Just be yourself. You're not writing the next great American novel, just about what you did and saw. Have fun with it. Let your sense of humor come out.
