Calling Carnival Cruise Line is honestly straightforward. The last time I called, it was because I was trying to surprise my sister with an upgrade for her birthday cruise. I figured it would be complicated, but the rep walked me through every category, explained which decks were quieter, and even checked for any special rates I didn’t know about. I appreciated how patient they were, especially since I kept changing my mind. Once we picked the cabin, they processed the upgrade right on the call and emailed the new documents instantly. If you’re doing anything that involves changes, adjustments, or special requests, a quick phone call is the easiest route—no guessing, no back-and-forth messages.
