I traveled on the Carnival Destiny with my husband and three kids aged 4, 9 and 12.
This is our third cruise, second with Carnival. I have to say, we won't be cruising again for a long time. We sailed out on New Years Eve...
Here's an overview.
The cabin itself was clean and had a lot of drawer and closet space. however the bathroom reeked of sewage. While on our balcony all we could smell was cigarette smoke.
