Welcome Rachel ~
That is a great question and I love to see that you are planning ahead.
Electric Conveyance Vehicles (ECVs) are available for rent at all Walt Disney World Resort theme parks, water parks, and Disney Springs. A refundable deposit is required in addition to the daily rental fee for ECVs. When exiting whichever location you are visiting, return your ECV to the rental location to get your deposit back. Deposits are typically higher at the water parks and Disney Springs than the theme parks. Length of Stay Rentals are not available for ECVs.
ECVs may not be removed from the destination where they were rented, but you only have to pay once per day to rent an ECV. If you plan to visit more than one theme park during a day, you can show your receipt at the ECV rental location in the next theme park to get an ECV. This is based upon availability as there are a limited number of ECVs. If you plan to leave and return to the same park on the same day, your ECV can be held for you.
ECVs are available on a first-come, first-served basis and reservations are not accepted. If you are visiting during a peak season, I would recommend arriving early.
If you feel that you would need to use the ECV outside of a theme park, there are several Orlando-area companies that also offer ECVs rentals. Pre-orders and deliveries to Walt Disney World Resort hotels are available through these providers. You can find a suggested list of local companies on the link provided above.
Please feel free to visit us again with all of your planning questions. We are hEAR for you!
Wishing you minnie magical memories :-) Allison V.
