Lovely video, thank you for sharing. I'm taking my daughter and her boyfriend in August and he's not been to any of the ports (or on a cruise for that matter) so looking forward to seeing it through fresh eyes.
I've always had to cancel, lose my deposit, and rebook to get any price reductions in the past. I was told this is because we have ABTA and ATOL protections so there's no way to adjust without cancelling.
