I can’t remember exactly where I found it - I think it’s when I was scouring their cancellation policy because I needed to change our august sailing. I hadn’t heard anyone mention it before but I rang them and they confirmed it was correct. I moved my sailing to 2025 under this option, they just transferred my deposit over and I didn’t lose a thing. They certainly don’t advertise it as a ‘perk’ but I assure you it’s correct!

If you are Captains Club Elite or above you are entitled to one free change which includes cabin location, category, sail date etc. of course you will pay the going rate (which can work in your favour if prices have gone down).
