On a scale of 1 to 10, the Carnival Vista was a 9.8! We loved it and were trying to find a way to hide during debarkation and stay on board for another go round. ;)
The Vista is brand new, clean, and beautiful. There was so much attention to detail in the designs of the eating areas and the Lido deck. The staff kept everything super clean. The Skyride was more fun than I expected. It actually drops down a hill and swings like a suspended roller coaster. The ropes course is divided into easy and hard, and the hard side was comparable to regular (on the ground) ropes courses I've tried. The Serenity deck in the bow is great; it has wicker chairs that curve over your head and matching foot rests. It also offers large hammocks. We went to an IMAX movie, and were impressed with the theater size and quality.
We had an outside stateroom and were pleasantly surprised. The room was bigger than we anticipated, and it had two bathrooms. One had a small tub and shower; the other had a larger shower and a toilet. The staff was great
The cabin was super clean and bigger than we expected. We had four people in one stateroom and it was worked just fine. The beds were all comfortable, and the stateroom came with two bathrooms. One had a small tub/shower combo, and the other had a toilet and shower.
