Welcome, Christy! Like Tigger, I enjoy bouncing around, so I love your plan to park-hop during your upcoming 
Walt Disney World Resort visit. You'll be here before Pooh can say, "Oh, bother," so let's hop to it to plan your day.
Utilizing the 
Park Hopper Option to its full potential is admirable; I salute you, Christy! You can absolutely use that ticket to hop between three parks. My pal 
Amy recently visited all four theme parks in one day with her park-hopper ticket! Was she tired? Oh, yes, but she had a magical time.
I'm sure you want to spend every possible second in the theme parks, so let's look at a plan to visit three parks efficiently. Traveling between the parks can be time-consuming, but I have some fun, free, and fabulous ideas!
Start your day at 
Magic Kingdom Park early. Be there at park opening and experiences a few must-do attractions when wait times are typically low. I always head to Seven Dwarfs Mine Train to start my day with sparkling gems! 
Next, travel to 
EPCOT aboard the iconic monorail. This is an attraction in itself! Check out some artist booths at the 
EPCOT International Festival of the Arts, and sail above the clouds on Soarin' Over California. 
Finally, you'll take the Disney Skyliner to 
Disney's Hollywood Studios from the International Gateway near the France Pavilion. Spend some time at Star Wars: Galaxy's Edge and pilot Millenium Falcon: Smugglers Run. Use the Single Rider line, if available, to save a little time.
Other ways to travel between parks include using your own vehicle, a ride-share service of your choice, 
Minnie Van Service, or Disney Bus Service. The Disney park magic is at your fingertips!
Christy, bouncing is always fun, fun, fun! I know your visit will be full of memories. Be sure to wear comfy shoes! Stop by 
planDisney anytime.
Magic awaits,
Elaine
