I have sailed multiple ships in the Fantasy class, Paradise included (back in '03 when it was still no smoking). Due to this, I knew going in how this ship would compare to newer offerings from Carnival and competing lines.
First of all if you are capable of "making your own fun" you will probably have a good time on this boat. I started cruising in '95 (I was 21 then), so I'm familiar with the activities boats of this size typically offer. If you are content with the pool deck, casino, meals, comedians, and maybe a show or two you should be fine. If all you know is Carnival Fun Ship 2.0 (upgrade) boats (or RCCL for that matter) the Paradise may seem kind of boring.
Typical inside cabin.Only cons were slightly worn carpet and cabinetry and a yellowed robe.Beds were comfy and the bathroom clean.
