After your first cruise you will earn 10 points for every dollar spent on the "cruise fare" not the land or air portions JUST the cruise fare. When you get 50,000 points ($5000 spent) you get $200 off the next cruise. You can also earn and use points for other prizes as well within the Carlson companies. Friday's is a Carlson company for instance.
A family only needs ONE card as if there is one card in the cabin that card gets points for both people. This way you build up points faster.
Some like to have two cards if they are active in any special offerings that gold points has - like "give us your new email address and we give you gold points" Not major promotions usually.
However you cant combine the husband and wifes points unless you get a "household" account which in turn results in ONE card.
No gold points on 2 for 1 cruises Maskai so it wont hurt to get one but you wont gain points this time. The first cruise is only 5 points per dollar but this cruise will at least qualify you for the 10 points a dollar level.
Redemption is EASY. You just tell your TA how many points you have and the TA takes it from there.
