It also depends on what sailing experiences you have had, where you have been and your stage in life.
We have experienced various lines, done over 60 cruises, been everywhere we wished to go. Highlights being, Gallapagos, Norway, Dalmatian coast, Hawaii, Baltic etc.
Our focus is very different now, not itinerary driven, but food, the ambience, meeting people. So far this Oceania has done this for us more than any line and we hope it continues to do so.
There are times that we will not get off in some ports...there are other times that we will revisit the places we have been to before. Now rarely doing tours. Love to get a map, walk for hours, explore.
