Celebrity ships on a seven day run of the Millie class for sure have a great kids program and facilities. The facilities of course are there all the time . I would think that the Mercury and the Galaxy would also but I do not have personal experience there. The Zenith & Horizon have much smaller rooms and generally do longer cruises. So along with them and longer cruises with the other ships I would hesitate to book with kids. The shorter the cruise = more chances of kids in my experience.
