We've sailed on every ship, and we consider both. Each ship has different feature shows, and being able to see the different shows is meaningful for us. We prefer the Dream class ships in general due to their better amenities. However, itinerary matters, as well. You can't currently sail a Dream-class ship to Alaska, so we sailed there on the Wonder, even though for other itineraries we wouldn't sail on her due to the lack of major waterslides. So both ship & itinerary are important to us. We look forward to the new ships coming out, and plan to sail on each one.
