I have a Sea Miles card. I haven't tried to actually use any miles yet. (I'm not sure how many I need) But I did check the web site and there are more than just the Carnival Cruises listed. So, yes, I am sure.
Anyone ever use there miles for a cruise? Did it really save you any money and do you have to go through their travel agent to get it?
