Which cruise has the least amount of revisited ports? Which cruise has the most sea days? If a lot of sea days which ship would you be the most comfortable especially if you have to sit inside? If a cold weather cruise everyone rushes to sit in the atrium during the day. We go for the itinerary. If port intensive we like a sea day between ports, if possible. We lean towards the older ships. Have done both types. The newer ships for us are nice but not as comfortable feeling. Tough call.
