Yes, really. Look at the crazy stuff people complain about where they claim "I'm switching cruise lines"
Well it works in the positive to be a repeat customer, too.
If you have the same last names, you need nothing more than the child's passport.
If there are different last names, you are still probably OK, but can't hurt to bring something proving the relationship just in case.
Plus a ship bar isn't a bar in a vacuum. It's part of a larger vacation experience.
Making a customer feel special because you give them a free or stiffer drink may well make them book another cruise. Giving away $5-10 in alcohol but having that customer turn around and spend a few thousand on another cruise...not a bad strategy.
Man I'd love to be on board when this happens.
I frequently get F-18s or F-16s fly about 1500 feet overhead, plus some C-5s or C-17s looking like they're going to land in my back yard.
There was a survey recently that found that the percentage of first time cruisers who planned to cruise again was up significantly compare to what it was before the shutdown.
