thank you. what would I plug in for key words to find the idiosyncrasies? I have Never cruised. After 30 plus hours of research I had found out that only 3 lines goes to glacier bay (princess, HA, NCL) but that's the only details I know about the actual differences between lines in Alaska. Would you mind sharing more please? Does one get you closer to ports and therefore you're off the boat and on with your day faster than another? etc etc?
