Hi Susan,
Obviously I am a little biased, but I say a trip to Disney hands down is the way to go!!!
There is so much for them to do and experience!!! Your little ones will love the Magic Kingdom, and Disney's Animal Kingdom. Those would be my top two choices for you.
There are age and size appropriate rides, shows/parades/fireworks, character meet and greets!
I think both of your kids would love to get a hug from Mickey and Minnie! Or have a meal with Cinderella!!
It is so exciting to be at Walt Disney World with your little ones.
You will have such an amazing time that you will be booking another trip back once you get home.
Here is the link for the
Magic Kingdom and
Disney's Animal Kingdom. Take a look at all of the attractions and experiences. You can find out more about character dining

Please let us know if you have any questions.
