I wouldn't try and force her into it, or "convince" her. I would, though, try to talk through her concerns with her, and if she still isn't interested, ask if she's okay about you going with the kids.
FWIW, when we took our cruise in the fall - first cruise ever - I made a post that said, "We're both scared of cruises, and [wife] hates Disney, so logically our next vacation is a Disney Cruise." It sounds like a punchline of a joke, but it's totally true.
My fears weren't reasonable, so I could remind myself of that and get over them. My wife:
*doesn't like people
*doesn't do well in crowds
*was pre-med and knows too much about transmission of viruses & so was terrified of getting norovirus
*was a cook and so knows too much about food safety and public sanitation and so was paranoid about getting food poisoning
*is generally anxious and was terrified about our kiddo (then 9) going overboard
A big part of the reason she was willing to say okay to a cruise was that it was on DCL, b/c they have good track records in terms of cleanliness and food handling and safety. She hates crowds (gets panic attacks, so it's not just "hates"), so avoided the places and events with large crowds when possible (she didn't come to the halloween bash, and stayed in the back during the halloween tree lighting. she didn't go to the shows in the theatre. so in terms of crowds, the only real times she had to deal with them was embarkation/disembarkation, really. During the pirate party, she found a table off to the side and sat there; during the sail awave party, we watched it from one deck up where there were far fewer people. Our trip also went to WDW at the stop in PC, and we decided to play that one by ear, and she ended up not coming. (She really enjoyed the day on the ship with only about 60 other people!)
So - there are ways to do it that can help alleviate her worries (though there's never any guarantee you won't get sick. My wife did end up getting sick at the end of the cruise in the end), and I feel like that's different than trying to convince her she's wrong. But if they're big enough worries that she can't move past them - that's okay, too.
And, if it helps, for what it's worth, we're saving up and trying to find ways to cruise again, so clearly my wife has gotten over those worries. ;-)
