Haley, welcome to planDisney! I'm so happy you've stopped by with your question.
With the
EPCOT International Flower & Garden Festival in full swing and warmer, summer-like temperatures, April is a beautiful time to visit the Walt Disney World Resort.
Now, you are correct that for a portion of your visit, there will be a few runDisney events for the Springtime Surprise Weekend, but I'm happy to share that none of these "extras" will hinder your ability to enjoy the parks. Check out
THIS PAGE that shows all of the events that will be taking place from April 13th through April 16th. You'll see that all events are at EPCOT, Disney's Hollywood Studios, and the surrounding area. The runs all begin at 5:00 AM, so parks are open to regular guests after the runs conclude. You can take a look at the park hours for each park
HERE to help plan your itinerary.
Haley, I truly hope that your family's Make-A-Wish trip is full of Magic and pixie dust. If you have any additional questions, please come on back to planDisney where my fellow panelists and I are happier than Buzz Lightyear directing Star Command to see a returning guest.
Lauren
