My darling wife and I just returned from a 14-day cruise. We took over 400 pics and a few mpegs as well. It is true that not all of the pics are keepers, but how do you know which ones until you get them the computer screen? I suggest getting more memory cards. They can be bought fairly inexpensively, if you look around. The memories they provide lasts long after the cards are paid for. I really dislike having to ration my picture taking. I like to shoot away and see what we got when we get home. Enjoy your cruise, whatever you decide to do photo wise.
