When planning a Carnival Cruise, it's not uncommon for travelers to make changes to their bookings, such as adding a new passenger to their cabin. Fortunately, updating your Carnival Cruise booking with another guest is a relatively straightforward process that can be completed online or through the cruise line's customer service. To ensure a smooth and hassle-free experience, it's essential to understand the steps involved in updating your booking with an additional passenger.

Adding a New Passenger to Your Carnival Cruise Booking: Online Process

To update your Carnival Cruise booking with another guest online, you'll need to log in to your account on the Carnival Cruise website. If you've already created an account, simply enter your login credentials to access your booking details. If you haven't created an account, you can do so by clicking on the "Create Account" button and following the prompts. Once you're logged in, navigate to the "Manage My Booking" section and select the booking you want to update. From there, you'll be able to add a new passenger to your cabin by entering their details, including their name, date of birth, and contact information. Be sure to review the additional fees associated with adding a new passenger, as these can vary depending on the type of cabin and the time of booking.

Verifying Eligibility for Adding a Passenger

Before you can add a passenger to your Carnival Cruise booking, you must ensure that you are eligible to do so. Here are some factors to consider:

  • Check your original booking type: If you booked a stateroom that has a maximum occupancy limit, you may not be able to add additional passengers.
  • Review your cruise itinerary: Some cruises may have restrictions on adding passengers due to space or capacity constraints.
  • Check your account status: Make sure you have a valid account and that your booking is in good standing.

  • The passenger's passport information (if applicable)
  • Proof of relationship (if applicable)
