To remove individual port stop line items with $0 amounts from your cruise pricing, go to the pricing tab of your itinerary, expand the cruise package that was automatically created, check any box within the expanded package, click the gray box with a dash (–) to select all items in the cruise package, choose 'Remove from trip package', delete the now-empty trip package, and click 'Publish' to apply the changes. This will remove the $0 line items while keeping your cruise and all port days in your itinerary.
