For one thing, I have never seen a post on this or any other cruise board which complained about fellow guests because of their tatoos. So I don't think "tatoo prejudice" is a big problem among the cruise crowd. And, as I said above, more depends on how the person with the tatoos otherwise presents himself/herself than the tatoos themselves. Then, there is the question of what we mean when we say "tatoos". Are we talking about a person with one or a few tatoos, or are we talking about someone who is covered with them like the "tatoo lady" at a circus sideshow? Anybody who is shocked by a person with one or a few tatoos doesn't get out much! But I think many (including those with a few tatoos) would be shocked to see a person covered with them on a cruise.
