Although we have taken several cruises, we have not done a Back to Back on NCL. We are booked to do this in October. I have some questions about this. 1. Is there a number to call with NCL that allows you to link these 2 cruises as can be done with other cruise lines. 2. Can you check in for both cruises on the first cruise or do you have to disembark (go through immigration, etc.) and then recheck in. 3 . If you are in same cabin for both cruises, can you leave luggage in room after first cruise or do you need to send it out and then recheck it. Any answers to above questions will be greatly appreciated and any other helpful insight as to B2B with NCL would be welcomed.
