I have cruised about 25 times, about half on Carnival and half Holland America. The Fascination is a nice size, and it's easy to navigate.
I stayed in an inside cabin, which was clean and comfortable and had plenty of storage. It was quiet, most of the time. There are always a number of annoying passengers (on any given Carnival ship) who are boisterous in the hallways of the cabin area way after midnight, so I bring earplugs. It helps.
I absolutely loved the attitude of the employees! They were efficient, and courteous, without being overly 'friendly' with a lot of forced concern.
Comfortable, cozy, clean, good storage, well maintained, comfy bed.
I live thirty minutes away from the port and I often wonder what exactly people do in Jacksonville. There's not much near that port.
I like to walk around the city streets and enjoy the sights and sounds of Nassau. I especially like the Straw Market. It's about fifty shops, all selling the exact same thing, manned with pushy sales people who want to 'make a deal'. I love it though, and go every time I'm there.
