Look back in this thread about Wilderness Lodge. They accommodations for Tesla owners to use our portable charger. Not the greatest but it's a start. Talking to management earlier this year, they stated you're going to see a lot of attention paid to EV charging. Disney tends to work slow though so we'll see how long it takes. They are fully aware of the changing tide.
The chargers at Epcot are fee based but it's a solution. We live 40 minutes from Disney and are there frequently on weekends. It's rare that we see the chargers ICED. The bigger problem is that they are always full of Teslas. It's not uncommon to see 5-10 Teslas up in the front parking area near the chargers.
