How to Cancel a Cruise I Purchased?
You'll need to contact whomever you booked your cruise through for assistance. Contact information for each cruise line can be found at: https://cruiseline.com/advice/before-you-cruise/what-to-know/what-s-the-easiest-way-to-reach-your-cruise-line-.
Shipmate price searches allow you to compare prices from multiple travel agencies and cruise lines in one convenient place, but your booking is handled by whichever site you booked through.
Not sure who you booked your cruise through? Check your e-mail or credit card statements to see who charged your card.
