Hi Jean -
Thank you for visiting the Disney Parks Moms Panel site! With the repositioning of the Disney Wonder ship last 2012, DCL has not offered the Mexican Riviera sailing back on their cruise itineraries. New itineraries are always being reviewed and changes do happen often. I was fortunate to have been on a 7-day Mexican Riviera voyage a few years ago, and I know that it's a great itinerary for families, especially for those in the west coast. We'll just have to watch out for future news, whether or not DCL returns to Mexico.
As an alternate west coast sailing, DCL offers the
California Coast voyages. These are offered out of San Diego, CA and Vancouver, Canada. But, these sailings are scheduled for the summer time only. All the other December 2014 and January 2015 voyages are scheduled out of the east coast (Port Canaveral and Miami, FL). Hopefully, there's a voyage that will fit your schedule that may be a fit for you and your family on the DCL
Cruise Search site.
Sorry, I don't have better news. But do let me know if you need additional information or need help in planning an alternate cruise.
Have a great day!
Dolly
