Welcome Aboard, Santiago!
Thanks for stopping by the Moms Panel with your question.
I've looked at the sail dates for 2015, and on May 4th, the
Disney Wonder will have headed out to sea on a 14-Night westbound Panama Canal cruise that departs on May 1st. If it's the sail date that you're interested in, and not the particular ship, the
Disney Dream will be departing from Port Canaveral on May 4th for a 4-Night Bahamian cruise. I've checked availability on Disney Cruise Line's official website, and there are still staterooms available for that sailing.
You can book your Disney Cruise by visiting the website
here, contacting an Authorized Disney Travel Planner, or calling Disney Cruise line directly at (800)951-3532.
I hope this helps with your planning. Have a magical day! - Diane W.
