Each of the 4 Theme Parks have Electric Vehicle Charging Stations available on a first-come, first-served basis.  There aren’t many, however.  At our last check, there are less than ten available at each park so you’ll need to check with a cast member for the location and availability.
There are also Charging Stations at Disney Springs, Disney’s Riviera Resort, Disney’s Coronado Springs Resort and Disney’s Wilderness Lodge.
KNOW BEFORE YOU GO:  You’ll need to download the ChargePoint App – as this will enable you to pay the fee for the charging while you park there.
