Loved the Fantasy. We did a four night cruise last December. It was just my husband and I but there were plenty of kids. When I peeked into the kids area, they sure seemed like they were having fun. Even though it was only 4 nights, it seemed longer because there was so much to do we didn't sleep much. See my pictures in the phot gallery---Carnival Fantasy author Cheryl C
I'm taking my grandson (14 years old) on a 4 nighter on RCCL in two weeks, stops in Key West, Coco Cay, and Nassau. I live in south Florida and it's an easy drive to Miami. Living in Florida, I don't have to worry about air fare. My grandson chose this itinerary because he prefers stopping in ports rather than sea days.
