WHile this has to be your personal decision, I am not one to panic and cancel travel. I figure that I have as great a chance of some mishap/disease here at home in the NY-NJ metropolitan area as I do on the road.
Perhaps you should carry lots of Purel around to keep cleaning your child's hands rather than cancel the cruise. Ultimiately, though, it has to be your decision and what you're most comfortable with.
