Enchantment of the Seas 2021-22 Schedule

[st5310]

We are interested in a New Years cruise on Enchantment of the Seas that would embark on Dec 31, 2021, but cannot find a sailing for that date.  There is an Enchantment sailing that leaves December 23rd, but the next one doesn't leave until January 28th.  The ship disappears from the schedule between Dec 31, 2021 and January 28, 2022.  The only thing I can conclude is that the Enchantment is going into dry dock or has been chartered for those missing dates.  Anybody know anything about this?  Or might there be another reason for the gap in the sailing schedule?  Thanks.
