Looking at all options to cruise Hawaii again. Did NCL several years ago. Plus side- great way to see the Islands. Went to both sides of the big island, had overnights in Maui and Kauai. Cons- all American crew that did not have the same incentives to work 12 hour days for 6-10 months. Service was awful. Con for me was no sea days but that might be a plus for you. Flights were very expensive and you need to stay a few days in Oahu to see that island and the hotels are not cheap. We stayed 3 nights precruise so we could have done. 10 night cheaper. It was a great way to see the islands but now I'm looking at round trip California or Seattle. Don't want the long flights to or from Hawaii or Vancouver. Several cruise lines only cruise one way to Hawaii. Some don't go to Kauai. Few go to both Kona and Hilo. Like the idea of the sea days. Originally looked at January but I'm reading the seas are rougher and the weather more rainy. Now looking at April but expect more ships at that time. We went on NCL in August and it was great being the only ship in most ports.
