Here's the email I sent to Disney today:
We are Florida residents living in Sarasota. We typically visit Orlando several times each year, usually staying overnight for one or more nights at a convenient hotel. We have placed a deposit on an electric vehicle (Tesla Motors Model S), and will be receiving the car sometime this Fall. I was surprised to hear that Disney has no plans to accommodate guests who arrive with electric vehicles. We request that you consider accommodating at least a small number of electric cars in your theme park lots, and if you find that your charging stations are being used, you could expand accordingly. In the meantime, it could be a great marketing opportunity for you. From what I know about Walt, I believe he would have been an early adopter.
Since we are committed to purchasing our EV, we will still drive it to Orlando. However, we will plan our trips around whichever hotels and entertainment venues provide charging stations. Thank you for your consideration.
