You're absolutely right in saying that the Dawn Princess has a terrific itinerary. Unfortunately, it won't be sailing that route next year. The Sun Princess is doing something like it, however, so there IS another choice after all. Thanks for the heads up!
As for the Panama Canal, that's what I was meant--the Coral and the Island Princess are doing the exact same route all year with no variation, which seems odd. Wouldn't there be more repeat business if the two ships went on different routes? I guess what I should also have clarified is that Mexico and other Latin American ports are not all that appealing to us because we live on the border of Mexico. I like the culture, but we're hoping to try something that's a lot different from what we experience on a daily basis.
