I too am prone to say leave the child behind for a week. Yes, you'll feel guilty, but what an opportunity to relax. Taking a young child basically ties you down 24/7, all activity revolves around the child who doesn't even know he's on a cruise. Might as well call it a babysitting cruise. I think going on a regular vacation is fine, but somehow vacationing on a cruise is a catagory all it's own.
