Hi Kelley!
Great question! If you ask my husband, he'd say NO WAY is it too advanced! It's his favorite park. If you ask me, which you did, I say possibly. BUT, there are plenty of incredible attractions and visuals that will spark the interest of any guest, regardless of age. My kids are 2 and 5 and really enjoy visiting Epcot. What's great about it is that Disney has made all of the educational adventures that make this park so great, fun!
Pick up a Passport (for a small charge) before you enter the World Showcase. The kids can go from country to country and get their passports stamped. I remember when we first did this, my son was so amazed to see his name written in Chinese.
There are eleven
Kidcot Fun Stops along the way where your children can create and color a pretty cool souvenir to take home including stamps from each of the countries. These are also great for Mom and Dad to take a break OR for Mom to look around in the shops. (Hehe)
Our favorite attraction is The Seas with Nemo & Friends. After you take a ride through the "Big Blue World", you can check out some amazing sea life including dolphins, rays and sharks.
Stop back by if you'd like to learn more about Epcot with little ones.
Have a magical day!
