Hi William!
There are so many wonderful things to experience at Walt Disney World, especially with a 3 1/2 year old. That is a great age to enjoy many of the things that Disney has to offer.
I think your little one will love the
Art of Animation Resort. This resort has a fun theme, with so many of the Disney and Disney Pixar movies, including Finding Nemo, Cars, Lion King and Little Mermaid. The
Big Blue Pool is the biggest of any pool throughout Walt Disney World. The Landscape of Flavors also offers a variety of foods that both little ones and adults love.
Your little one will also love
Magic Kingdom.
Dumbo, Country Bear Jamboree and The Many Adventures of Winnie the Pooh are some of the favorites of the preschooler sect. You can easily search for the
attractions your little one will enjoy by filtering by "any height" and "preschooler" for the age interest.
Plan at least one character dining experience. I highly recommend
Crystal Palace in Magic Kingdom, as you can dine with Winnie the Pooh and Friends and there is a wide selection of food to choose from, even soft serve ice cream for dessert!
Magically,
Stacy
