Have to agree with BoatLover on two points...First, we love the Fantasy!! Second, I will be sailing on her for the third time this July. It's a smaller ship than the mega ones out there now, but I think that's why I like it so much. Plus they have recently done quite a bit of renovations to her. I have stayed in a Cat. 12 suite and last time in a Cat. 6C.....the suite was great, but IMHO I'd rather save the extra money and then not be so worried about my bar tab, especially when it's just a short 3 or 4 day cruise. I can't compare it to Disney since I've never sailed her, I can only guess that the decor might not be as impressive, but I don't think that will stop you from having a great time.
When are you booked for Carnival Fantasy? We booked for July 15th (3 day to Nassau)
