Hi, Esther and welcome to the Disney Parks Moms Panel!
This is such a sweet gesture to bring your mom to the happiest place on Earth!
Currently, Disney does not offer any senior discounts or free admission as guests under the age of three. A regular priced theme park ticket would be required for her to enter the theme park.
If you are concerned about paying a regular admission for your wonderful mom, how about character dining!
Advanced Dining Reservation can be made at any of the Walt Disney World resorts and do not require admission and if you're staying at one of the resorts, you can park for free. Oh, and if you're not, guests who have Advanced Dining Reservation at a Walt Disney World resort receive complimentary parking too!
Here's a list of character dining experiences and their location.
1900 Park Fare-Disney's Grand Floridian Resort and Spa
Chef Mickey's-Disney's Contemporary Resort
'Ohana-Disney's Polynesian Village Resort
Garden Grove-Swan Hotel
Trattoria al Forno-Disney's Boardwalk area
Cape May Cafe-Disney's Beach Club Resort
This will allow your sweet mother to see the characters, take photos, get hugs and be showered with all of the pixie dust she can stand!
Esther, I hope that you, your mom and entire family have the most magical time ever!
ChEARS!
Korliss
