Hi Martin! Welcome back to the Disney Parks Moms Panel!
Your trip is just days away! I'm thrilled that you are arriving in time to experience all that this
Incredible Summer has to offer. I hope you have set aside some time for exploring Andy's Backyard in the all-new
Toy Story Land at Disney's Hollywood Studios. It is amazing!
After speaking with a Cast Member, I learned that the
ECV rentals (or scooters) at the Walt Disney World Resort should last all day in the parks. I actually had a friend use one on our trip last year and there weren't any issues with her running out of battery all day. You will need to charge it each night to make sure it has full battery power each morning.
At the link for ECV rentals above, you can scroll down to the bottom and find other Disney Featured Providers if you would like to shop around for the best price and longest battery life. Contacting each provider separately will give you the details for all options.
Enjoy your upcoming trip, Martin! Please let us know if you have any other questions.
