I can't speak for the Hawaii cruise, because we sailed on Spirit for the Alaskan cruise. But as for the ship, we loved it. VERY good layout, the crew was excellent and the food was VERY good. The great thing about the Spirit class is that something like 80% of the cabins are balcony and I think 90% have at least an oceanview. That's why they use her for the Hawaii and Alaskan cruises, you get great views.
