Hi, Kerri!
Great question!
There is always so much to see and do during a trip to Walt Disney World; we've decided to keep our favorites in our plans while ensuring enough time to try some new things each day, including attractions, entertainment and dining options. You'll love it!
First, take a look at each park's webpage and read the descriptions of attractions you've
yet to see. There are often attractions which you might not have experienced yet but are really great; put them on your list for the day you're in that park. This will surely include everything in Magic Kingdom's New Fantasyland (which opened in December of 2012) as well as the new Test Track (also opened since your last visit.)
Next, consider dining in locations that you have yet to try. Both Quick Service and Table Service locations can be destinations unto themselves, so check out those which may be located in a nearby WDW Resort hotel or around a park corner you've yet to turn.
There are lots of
Special Events & Tours which you might want to experience, too, Nicole, so take a look to see what's offered.
Of course, the time of year you'll be visiting WDW will be important, too. If you are heading to Orlando during a different time of year than your previous trips, there will surely be experiences that you've yet to try.
Send another question including your dates of stay, Nicole, as well as where you'll be staying, if you're on a Disney Dining Plan and the ages of Guests in your party. I'd love to help you find what magic you've yet to enjoy on your next trip to WDW!
