I, along with my family took a 7 day Western Caribbean crusie on the Disney Cruise Line ship the Magic.
This cruise departed from Port Canaveral, FL and docked in Key West, Cozumel, Grand Cayman and Disney's private Island, Castaway Cay.
The cruise ship was very nice and very clean. There were many different activities for all age groups. This trip would be ideal for the parents of kids 5 years old or older. If they are older than three, they can be in the kids club, which seemed to be great.
If the kids are younger than 3 (which mine is) they have limited daycare availiable to you. This was nice for a few hours of relaxation.
I would not recommend this trip for people with no children, unless you really enjoy being around kids all the time. For families, this is a great trip option, especially if you are a fan of Disney.
