We have just received our cruise documents last week (sailing on Sept 5th). We have read the document enclosed and know that we have to sign all the documents/forms enclosed (cruise contract, embark form and payment authorisation form). Do we also need to do the online check-in?? Somehow I know people get to select port arrival time via online check-in. We are travelling on concierge (Cat V) and have been told that we do not need to select a specific port arrival time. Is this true? Will online check-in skip the step of asking me to select port arrival time? We will be staying at the Hyatt Regency the night before our cruise and plan to catch the first bus to the cruise terminal on day of embarkation (would like to maximise our time onboard).
