I just replied to a similar question......
Princess has an awesome Hawaii cruise on the Island Princess.
15 days from LA. 4 sea days out, 5 days of Hawaiian ports, 4 sea days back & Ensenada, back to LA.
I have done a Hawaii/Tahiti cruise that was just awesome. Moorea is one of my ultimate favorite islands.
If you have not yet done a Panama Canal cruise it is one to experience. I have done this many, many times & still love it.
Just returned from the Baltic, which was awesome. Very port intensive.
Have done the Black Sea & Greece. Looking forward to another Med. cruise. Cannot wait to cruise from Venice.
I am a sun lover, but, an Alaskan cruise is wonderful too.
Good Luck with your decision
