I chose Vista as it was a new ship and liked the promotional video. I didnt know much about Carnival at the time. The more I learned, the less likely it was that I was going to enjoy it. However, it was not bad at all. A few niggles, but nothing major apart from Carnivals mis management of information regarding VAT.

It was ok... no noise problems from below
