I boarded the Carnival Legend sailing out of Tampa around 12:30 pm and was on the ship within 15 minutes. It was a very quick check-in and boarding process. The Lido Deck with the buffet and pool area were very crowded as expected on embarkation day. Rooms were ready at 1:30 pm when the crowds started thinning out.
There are obvious signs of rust on the ship and wear and tear, but otherwise the ship was beautiful. On the last sea day sailing back to Tampa, my cabin-mate and I took the "Behind the Fun" tour and it was absolutely worth the price. It is an almost four hour tour that goes through out the ship. Photos are also taken in the galley and on the bridge, and delivered to your stateroom that evening at no additional charge.
We had Late Dining which really worked out great. The food in the dining room is good and portions are generous. Buffets were also good and well stocked for both breakfasts and lunches. There were a few different selections for breakfast throughout the week, but my favorite were the egg quesadillas! They were great.
The shows in the Follies Lounge were good as were the comedians through Punchliner in the Firebird Lounge. The entertainment in the other parts of the ship weren't as great as I've experienced on Carnival in the past.
We also scheduled a Cruise Critic Meet Up on the first sea day, which was a great way to meet others on the roll call. For a small fee per person, Carnival offered an open bar for an hour with several different drink choices and snacks.
The Serenity Adult Area for guests 21 and older is on the aft Lido Deck. It's nice, but as one fellow cruiser said "it's a bit too serene." I think some soft music in the background would have added to the ambience.
