Hi Angela,
How exciting to be returning to Walt Disney World for the first time in years! You are going to have a wonderful time with you parents. Visiting Disney Parks as an adult is an entirely different experience than going as a child. No doubt you will be blown away by how much things have changed. Based on the facts that you have eliminated Epcot as an option, and you are traveling with seniors, I would recommend that you spend the day at
Disney's Animal Kingdom Theme Park. This park has a very laid back atmosphere. In fact, our family considers it our "downtime park". My mom (in her late 60's) enjoys it the most out of any of the Disney Parks. The
Kilimanjaro Safaris is a wonderful attraction for all ages. You all can stroll on the
Maharajah Jungle Trek and
Gorilla Falls Exploration Trail together. Depending on whether or not your parents are daredevils, they may even enjoy
Kali River Rapids. It is one of my moms favorites. There are two "must-see" shows at Disney's Animal Kingdom: The
Festival of the Lion King and
Finding Nemo - The Musical. I believe that your parents will enjoy both of these Broadway caliber productions.
Wishing you magical memories,
Kaylene
