I've been on a few other Carnival cruises and a couple of other cruises with different lines, but my experience on the Carnival Paradise was the best by far. From our room steward to the food and activities on board, it was a great experience!
The Carnival Paradise is in the Fantasy class, so it is an older and smaller ship, but it does not lack in amenities or activities! I actually love this ship size, because it's easier to get around and doesn't feel overcrowded.
Our room steward was Robi, who was very friendly and helpful. We didn't need much extras besides a couple of towels and pillows, but he brought them very quickly. The room was also super clean. I've been on other ships where things like the fixtures are dusty/dirty, but that wasn't the case in my room.
We booked an interior room to save money, and the cabin was very nice. Very clean, and lots of storage. A family of four had no problem finding a place for everything, even though I felt we overpacked.
