I don't remember Disney as much as I do the Royal Cruises. I was 12 when I went on the Disney Cruise, but from what I do remember it was absolutely amazing. My parents still tell people it was the best cruise they have been on. I love cruising with Royal, but i'm just interested if Carnival will have more to offer for a 19 year old, and a 17 year old. I have heard many times its a 'party ship'.
