Well at $479 per person the price was right. Four of us signed up. My 60th birthday! We had side by side cabins and the balconies joined after we asked to have the divider opened. (they only do a limited number of these "openings").
The Port of Baltimore runs a class operation. I felt like they processed the crowd very well. The boarding went quickly and we were all directed to deck 9 to have a Buffet Lunch. What a zoo! Maybe if it weren't so cold more folks would have migrated to the covered pool area sooner. We eventually made our way there and stayed there during the sail away. Nice view of the Key Bridge. Our cabins were ready at 2:30 and we quickly dumped our carry-on and went back for sail away.
When I entered this ship for the first time I immediately though about Captain Nemo and the Nautilus. The decor just looked that way to me. If Carnival hasn't done it already they need to have a BIG TOGA PARTY as an all night event on every sailing. What a setting. It reminded me of an Art Museum.
Nice cabin (5155) Clean. Comfortable bed and pillows. Very easy to get to venues. Nice shower. Obstructed view balcony was acceptable for the price. Nice to be able to step outside and my wife is a smoker. Room steward sucked! Better luck to you!
