I remember someone got a cruise for 2 people for something like 500K points but I don't see any cruise at all now. Can anyone tell me whether it is gone forever or will it come back? Thanks
They are likely coming back, especially with a new partner on board. Those cruises go QUICK, probably quicker than anything else in the game.
There aren't any today, but yesterday I swear I saw a (sold-out) reward for a free cruise with MSC for 1,000,000 points.
Just keep in mind that (as with any "free" cruise) - you are likely still responsible for port charges and taxes (~$50 - $150 / person depending on length and ports of call) and the service fees (~$12/person/night on MSC). Still can be a great deal --- but no really free in the traditional sense.
