By your logic we should have been cancelled but have not to date; we lifted and shifted 2020 to 2021, then 2021 to 2022, finally in April 2022 l&s to October 2023. The deposit is only an FCC of the original extra 25% for the first cancelled cruise. It is a V1 with confirmed cabin number. At no time was it a guarantee cabin.
From this thread, the last known directly booked cabin was cancelled by Celebrity on 29 April 2023, although some TAs may have been late advising their clients but the TAs themselves would have been notified before 29 April. What cabins have you seen cancelled after this date thanks?
