Multiple guests in room - how to attach email addresses?

[Gma&Gpa]

There will be three of us in my room.  The others have also cruised before - but how do we get their emails attached to this cruise, so they get the same notifications, etc that I get?  If they just go into their carnival.com account and attach the booking number - will that automatically do that for them?

If they are new to Carnival, they can join the VIFP club.  That will sign them up for emails.  (And they should anyway to start getting credit for their cruises.)  If they are already members, they should be receiving emails.  No guarantee they will receive the same emails you do.  Seems to be hit or miss on the promotional emails people get - if you gamble or not, gamble a little, frequent cruiser, doesn't seem to matter.😁
