So, this is what I've worked it out with only a 12-night itinerary based on what other cruise lines have done:
Day 1: Apr 29--LA
Day 2: Apr 30--At Sea
Day 3: May 1--At Sea
Day 4: May 2--At Sea
Day 5: May 3--At Sea
Day 6: May 4--Hilo, HI
Day 7: May 5--Honolulu
Day 8: May 6--Honolulu
Day 9: May 7--At Sea
Day 10: May 8--At Sea
Day 11: May 9--At Sea
Day 12: May 10--At Sea (or Service Stop at Ensenada)
Day 13: May 11--Seattle (if stopped at Ensenada) OR Vancouver, BC if no stop at Ensenada
Not much of an island hopping as it takes at least 4-5 days at sea to reach Hawaii and back to the mainland.
Any thought?
