Thanks for taking the time to visit the Disney Parks Moms Panel, Elise! It sounds like you have an "egg-cellent" vacation planned this spring!
I spoke with Guest Service today, and they don't have their Easter Worship schedule published yet. However, if we base things off of previous years, there will most like be Easter Sunday services at
Disney's Contemporary Resort in the Fantasia Ballroom. Catholic Mass is usually at 8:00 AM and 10:30 AM. The easiest way to get there is to take the resort monorail from
Disney's Polynesian Village Resort. I recommend calling (407) 824-2222 as you get closer to your travel dates to see if they can confirm these times.
Afterward, you might want to consider staying for Easter Brunch.
The Wave... of American Flavors, also located at Disney's Contemporary Resort, is known for its delicious offerings (it's one of my personal favorites), and they have a special holiday buffet. To round out your day, ride the monorail over to
Disney's Grand Floridian Resort & Spa to see their chocolate Easter Egg sculptures, and then make your Mouseketeers extra "hoppy" by attending
Magic Kingdom Park's Meet and Greet with Mr. and Mrs. Easter Bunny in the Town Square Courtyard (the scheduled hours are usually 9 AM to 6 PM).
I hope you have an "egg-stra" special trip, Elise!
