This morning I got an email notice of cancellation of a Sliver Cloud cruise I wasn't even booked on! LOL!

Dear Esteemed Guest,

I am writing to inform you with great regret that, due to operational reasons, Silversea has had to cancel your booked cruise, departing March 17th, 2022, aboard Silver Cloud.


We looked into booking that in January when we were on the Cloud in Antarctica. We discussed with the on board cruise consultant, but we didn't actually book it.
