With itinerary and cost being the same, I agree with the PPs and would try out the Wonder. Since you have only been on the Dream before, it would be a change of pace to experience one of the classic ships. You might find that you prefer the Wonder, or you might find that you enjoyed the Dream better. But you won't know unless you try the Wonder. I really enjoyed the smaller size of the classic ships. My 12 year old prefers the Dream and Fantasy. So for us, it comes down to how much time off can we take, when can we go, and where do we want to go.
