We are booked for a 4day land 3 day sea package on the 20th of October. We are providing our own transportation and I was wondering what check in at the cruise ship would be. I was under the impression that all the check in was done when you arrived at the hotel for both legs of the trip. Is this true? If we don't have to do any formal check in at the ship, then what time would you arrive (we have our own transportation)?
