I have been on the Fascination twice - both the 4 Day Key West/Cozumel Run and the 3 Day Bahamas Run. The first time was my first ever cruise and I loved it. I thought that 4 days wasn't enough.
My second trip on the Fascination was during our honeymoon. We should have sailed on the Imagination, but Hurricane Wilma wrecked the schedule and we could not get flights to connect with the ship, so we moved to the Fascination 2 days later.
My first trip was great because I had never been on a cruise ship before. My second trip was after sailing on the Carnival Glory, and going back to the Fantasy class, they do seem somewhat smaller and cramped, but I enjoyed the trip non the less.
It is good to see that the ship will get a refurbishment, I did notice signs of wear and tear on my second trip.
