Hello! I am going onto my first cruise very soon. I just realised I need to select a "wellbeing check" time slot while checking-in on the web. However my flight lands slightly after the latest wellbeing check time available (still, 7 hours before embarkation), is that alright if I arrive later than the selected time? Also, I am trying to book shore excursions. When I navigate to "Manage my Cruise" on the website, it would show "Pre-cruise reservations are closed" or "available soon"; but when I click to the shore excursion page via email - I can see all the packages and excursions again. Does this happen to anyone else?
