...you can't get there from here. Let me back up a bit. We just got off the Ecstasy and had a great trip. Good food, nice employees, no complaints. Getting on and off the ship was very easy (we didn't need First to the Fun). The passengers were not rude, and no one dressed too trashy or complained about anything. Nassau was fine, and Half Moon Cay is even prettier then I remembered. Carnival has retrofitted this ship with a few balconies (which we opted for) and otherwise updated it as best as they can with flat screens, etc. The ship did list to the left at all ports including while anchored at HMC. She was fine at sea. Odd.
Here's the issue. The Fantasy class ships have numerous dead ends. You really have to plan your route and walk to the correct elevator/stairs. You'll have fun and they are great for 3-4 day cruises. But it might be time to begin phasing them out.
