Hi, Amanda!
Aw, that is so sweet that you are wanting something magical for your awesome parents! I am not really sure what you are looking for, but let me give you some ideas:
-Have a special delivery in their rooms from
www.DisneyFlorist.com. They can create the most magical gifts for any occasion.
-Book a wonderful dinner at a Signature Dining location like the California Grill or Yachtsman Steakhouse.
-Schedule a fun tour like the
Wild Africa Trek. They will love the adventure!
-Ahead of time, send them a package to their resort so it is waiting when they arrive. Maybe include a beautiful frame with their wedding picture, a memorable family photo, or something special to them. Include in the box an autograph book and tell them to meet the characters, a Disney Gift Card so they can buy matching T-shirts, and disposable camera so they remember to take photos.
I hope this gives you some ideas. Wishing your very lovely parents a wonderful WDW vacation.
