Hi Tanuja,
Your son is in for a wonderful treat at Walt Disney World Resort! There is so much to see and do from the youngest Guests to the oldest.
My son was 3-years old on our last visit and some of his favorite attractions were
Prince Charming Regal Carrousel,
Dumbo the Flying Elephant, and
Tomorrowland Speedway all at Magic Kingdom park. For a fun way to beat the heat, your water-lover may love to cool off at the
Casey Jr. Splash 'N' Soak Station. This is a really fun water play zone for little ones right in New Fantasyland. He will probably get wet so you may want to bring a change of clothes for this one!
The other park I would zero in on is Epcot. Both of my kids love visiting
The Seas with Nemo & Friends and the totally righteous
Turtle Talk With Crush. We spend a lot of time here, not just for the characters, but also for the amazing 5.7-million-gallon saltwater aquarium full of sea life!
Those are some of our favorites, but I know you will have a great time at all of the parks. Best of all, you get to enjoy them together. Have a great time and say hi to Mickey for me!
