Ahoy, Margaret!
Sounds like you will soon be sailing on a magical cruise aboard one of the magnificent
Disney Cruise Line ships. VERY EXCITING!
At this time, there is no mechanism by which you may apply theme park tickets to anything aboard a Disney Cruise. Some Disney Cruise itineraries stopping in Port Canaveral, Florida include a 1-Day Park Hopper Option ticket and round-trip transportation between the ship and Walt Disney World Resort. For example, the 7-Night Halloween on the High Seas Bahamian Cruise from New York with a Marvel Day at Sea; and
three seven-night sailings in the fall of 2018 aboard the Disney Magic.
All of the above being said, many guests book
Disney Vacations by Land and Sea with a few days at the Walt Disney World Resort and a Disney Cruise either before or after their stay in Orlando. Some prefer to book the two portions of their 'surf-and-turf' vacations together by contacting Disney Cruise directly at (800) 951-3532, or their travel agent. Other guests opt to reserve the land portion independently and separately. In the latter case, you can certainly use your theme park tickets to visit the Walt Disney World Resort.
I highly recommend a
Disney-style Surf and Turf vacation. Just like former Cruise Mom Karen, my family prefers to cruise first then do the land portion afterward. However, other guests like to vacation at the Disney theme parks first and then cruise later. Either way, you are guaranteed to experience a magical Disney vacation full of memories that will last a lifetime!
Ritzy ºOº
