Ahoy, Fiona!
I'm so happy to hear you'll be cruising with Disney, but even happier to hear your parents will be celebrating such a momentous occasion! I can't think of a more magical place to celebrate than on a Disney Cruise Line vacation.
Make sure to let DCL know you'll be celebrating a special anniversary during your cruise. You can easily have it noted on your reservation by contacting your travel agent or by calling Disney Cruise Line directly at 1-800-951-3532 (make sure to have your reservation number handy).
You'll want to stop by the Guest Services desk when you first board the ship to pick up some Anniversary buttons - cast members and other guests will have lots of well wishes for the happy couple when they see their celebration buttons!
I encourage you to check out the Gifts and Amenities
page on DCL's official website. There are lots of goodies you can pre-order to have waiting for them when they arrive. Champagne, flowers, stateroom decorations and more are available, as well as customized cakes. The cakes can be delivered to their stateroom or to your dining table one evening. Speaking of dining, how about an adult-exclusive meal at Palo? Or, maybe an afternoon of pampering at Senses Spa and Salon?
Make sure to stop by the lobby one evening to take advantage of the ship's photography services. A group photo might be the perfect keepsake to take home as a memento of their lovely anniversary celebration!
If you want to take the celebration to the next level, you might want to consider a Vow Renewal Package. You can find out more about these exclusive packages
here.
These are just a few suggestions to make the cruise extra special for your parents - I hope this helps! - Diane W.
