Hi Jane,
Thank you so much for visiting the Disney Parks Moms Panel with your question. It sounds like you have a wonderful vacation planned.
Disney's Saratoga Springs Resort & Spa is so relaxing and lovely.
There are
car rental services at Walt Disney World. One easy location is the
Car Care Center at Walt Disney World, which is located near to the Magic Kingdom. Both Alamo and National Rental Cars have locations here, and a complimentary shuttle is available to help you pick up and return your car. There is also an Alamo and National Rental Car location at the
Walt Disney World Dolphin Hotel. If you are visiting Epcot or Disney's Hollywood Studios on the day that you wish to pick up your rental car, the Walt Disney World Dolphin Hotel is a quick walk or boat ride from either of these theme parks, so this could be a good option.
I hope that these thoughts are helpful for you, Jane! Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions.
