I have only ever experienced a Carnival cruise (hated it) but would really like to try a DC next year. Is there a big difference between ships like there is among the Carnival ships? I do plan to go out of Florida or Texas if that helps any on what ships would be an option for me. This would also be a first time cruise for my kiddos ages 17, 15, 9 at the time we would cruise. Thanks for any information.
