Disney Springs

Disney Springs formerly known as Downtown Disney is the best Disney Themed place for your buck! A visit here makes you feel like you have ALMOST gone to a theme park but for free! There are tons of shops some with interactive things to do. We love the World of Disney store. There is so much to see. Our favorite Disney characters are everywhere we look! We always stop at Goofy's Candy Company and get an ice cold Glacier slushee! There are always school chorus and band groups playing at the amphitheater. My daughter Natty Bear performed there too!

We like to visit Disney Springs multiple times a year. My kids and I have been here so many times we decided we would put together a Scavenger Hunt of things to find and Do. Please click the link below to visit our Scavenger Hunt Page.
