866-227-1888 helped me the first time I had trouble printing my Carnival luggage tags. For some reason, the “Print Documents” button wouldn’t load on my laptop. I thought it was a browser issue, but even switching didn’t help. I called, and the agent emailed the tags directly as a PDF so I could print them without using the portal. She also reminded me to print an extra copy just in case. Since then, I always check my documents early—learned that the hard way on my last cruise when I waited until the night before. If the site glitches, just call; they’ll send the tags right over.
