I doubt guest relations would be on the ship, however there is more than essential crew even in dry dock with no guests. My brother goes back on in 2 weeks, he’ll fly to Europe and join the ship there. No guests for the forceable. He’ll be carrying out his regular contract (10weeks on, 10 weeks off). The captain will not be on the ship, he’s not required. My brother is quite high up (one below the Captain). The children can be homeschooled on board (obviously not applicable for babies). I wonder if she’s not going on due to her health issues (she had a pacemaker fitted whilst pregnant)?? Maybe she’s changed roles after her maternity leave?
