We were very pleased with Princess to Hawaii.Well, we did DCL to Hawaii, now we're thinking about going on Princess.But, I'd do DCL again, too.
Our cruise director Dave Cole was fantastic (he's been visiting the islands for 37 years). He's very generous with first hand information about the ports. In other words, he does't just push the shore excursions. For example, he hosted an informal meeting for people wanting to dive or snorkel on the islands. As a certified diving instructor, he shared his favorite sites and how to get there without an excursion. To facilitate sharing private transportation, he had a sign up sheet, which he photocopied and distributed to those attending. This went well above and beyond what a CD typically does.
BTW, on the last night when the Cruise Staff performs "If I were Not Upon the Sea," he's the one wearing the tutu. (Where did you think DCL got it from? CD Brent worked for Princess before he moved to Disney.)
