Hi, Rachel!
Wow! What a fantastic idea about an Easter Sunday special!
Here are some things that come to mind:
take a look at Disney Floral & Gifts Easter offerings which would surely make a big surpise hit in your room;
in-room celebrations, too, would really wow your family on Easter Sunday.
If you're staying at a Walt Disney World Resort hotel, you might not know that you can actually ship boxes down to your resort, to your own attention, and your resort will hold your package for you until your arrival. At the time of this writing, the fee for this convenience is $10 per package. If you want to be really sneaky, you could pre-arrange some special items from home, such as a favorite Easter basket or a "home state" special treat, wrap them up in pastel paper and ship one for each of your children. (Imagine...Special Delivery from the Easter Bunny...he knew where to find you!)
Of course, if you're looking for a special Easter Sunday Breakfast, you might want to consider something such as 1900 Park Fare, which is at Disney's Grand Floridian Resort and Spa. Our breakfast there with Alice in Wonderland, Cinderella and other Wonderland friends had a very special, springtime feel to it...and we were there in August! The resort atmosphere is very elegant, yet kid-friendly, so it could be a real treat to have your Easter Sunday breakfast or dinner there.
Please ask any additional questions that you may have as you plan your truly spectacular vacation!
