The food was terrible in quality and there is always massive confusion regarding offshore excursions with Cunard (eg. we waited nearly 3 hours for the tender at Maui, thereby losing half the day at this port!) Only one fellow with glasses and a walkie-talkie had any organizational skills whatsoever.
The islands of Maui, Kawai and Hilo were beautiful and the people were also very friendly and helpful throughout the islands. This was the best part.
My other complaint with Cunard is that there were unruly children jumping from the hot-tub platform into the pool. Nobody else could use the pool unless they wanted to risk being hit by flippers from the children's snorkel gear. No point complaining to Cunard as they are indifferent, especially under this new management.
