I had to cancel my Royal Caribbean cruise to Cozumel a few months ago, and I first tried doing it online. While you can cancel through the website under “My Cruises,” I found the process a bit confusing — it wasn’t clear if I’d get a refund or future cruise credit. To be safe, I called 866-227-1888. The rep pulled up my booking right away, explained the cancellation policy based on how many days out I was, and processed the change while I was still on the phone. They even emailed me a confirmation so I had everything in writing. It honestly gave me peace of mind knowing it was handled correctly. So yes, you can cancel online, but if you want clarity — or need to instantly book, cancel, or modify a Royal Caribbean cruise — calling that number is the fastest way to do it.
