While I sail on Celebrity, RC (upcoming Symphony) and NCL, I’ve taken the family on both Disney Dream and Fantasy. The grandkids were in the same age group as yours are when on the Fantasy, a little younger when on the Dream. The service exceeds any I’ve ever experienced on any cruise line that I’ve sailed, however you do pay a premium price for it. The children’s club is fantastic! Disney is about kids....so there are lots and lots of kids everywhere . Disney characters and Princesses through out the ship is a sight for any age especially all the Star Wars characters on SWDAS. And Disney’s entertainment (shows) is amazing. Should you decided to sail Disney I highly recommend Star Wars Day at Seas on the Fantasy even if your children are not big fans. It was an experience that all in my family will never forget. My opinion for what it’s worth is that your children are at a good age for Disney as were mine, so if you are considering this option perhaps now might be a good time. I’ve read many reviews about the RC kids’ activities which all are very good. My Grandkids are now a couple of years older and were on the Allure last year and did not want to join the kids’ club. They grow up fast.
