Very nice cabin amenities on Disney (much better than the shower dispensaries on many other lines).
What lines have you cruised before? Disney, IMO, is somewhat different (in a better way), than other lines, although I still love Royal Caribbean.
We've been on NCL twice, RC once and Carnival four times. Our last cruise with Carnival was somewhat disappointing. We most likely won't do Carnival again. Anxious to try Disney. Our kids are grown so no little ones but we love family atmosphere.
