We are traveling with another couple in separate cabins. We are linked for dinner service. Is there a simple way I can do their check in so that we get the same check in times? I thought there used to be a link for check in. You had to have the booking number, the last name, the ship’s name and sail date. I normally do my check in at midnight. I think the last time I used the Celebrity app. I checked on my booking to see if I can link but I didn’t see any place to do that. Thanks.
