Just got back from the Fantasy today and thought that, for what it's worth, I'd write up a review. This being our first cruise, I know that some of the reviews were really helpful so here it goes...
First, traveling was me, my wife and 2 sons (3 and 7). I need to start off saying the weather was less than ideal-rained a couple of days, only saw a sunset the last day of the cruise, and rarely could see the horizon or the stars due to the rain and cloud cover. (I also know this is not the fault of CCL, I think). Our cabin was U193 (aft) and was nice-very little motion, and very little noise (except when arriving, and leaving the ports).
We stayed at the Radisson Port Canaveral and did their park and shuttle ride over to the port and this worked out well. They have a great pool, and the kids really loved that. Rooms were a little dated, but the grounds were fairly well kept. The area where you park your car was not secure, as in being surrounded by a fence or anything, but there must have been a few hundred cars in the cruise lot, so many people do seem to use this service. Had no problems getting to or from the ship.
