Since I've got a few pictures from my cruise, I decided to make a few Carnival Valor page backgrounds for scrapbook. I created the image of the ship and added the distinctive carnival "whale tale" on the back. I welded in the title with the shadowing. I don't know how much use it would be to you if you didn't go on the same ship, but I'll share the file.
The second picture is more of a "frame", It shows the front of a cruise ship on the right with moon hanging in the left. Here is the link to download it. You can always add your cruise ship name at the bottom. I used the ravie font, but you can use any you like. I used outset 3 times to make the outline.
