Hi, France! Welcome back to the Disney Parks Moms Panel!
Getting between Epcot and Disney's Hollywood Studios is a pretty easy trip, as these two theme parks are close together.
I would suggest taking a Friendship Boat from Epcot and cruise along Crescent Lake to Disney's Hollywood Studios. You will exit Epcot in World Showcase, and the entrance to the Friendship Boats are just to the left. Your cruise on Crescent Lake will take about 20-30 minutes, as you will stop at 2 Disney resorts and
Disney's Boardwalk before you arrive at Disney's Hollywood Studios.
You can also walk between the two theme parks. This walk will take you while and depending on the weather, it could take you longer.
Taxis and Ubers are available for guests at an additional charge if you find yourself in a hurry for a dining reservation. To use these modes of transportation, you will need to exit the park in Future World, near the Monorail and bus areas.
Enjoy your time at Epcot and Disney's Hollywood Studios! If you have more questions, please visit with us again!
