Hi Catharena,
Thank you so much for visiting the Disney Parks Moms Panel with your questions.
Disney's Saratoga Springs Resort & Spa is a lovely resort. It is very peaceful, and a relaxing place to have as a home base while on vacation at Walt Disney World.
I have good news for you. I spoke with a cast member at Disney Vacation Club today, who let me know that the villas with roll-in showers are sprinkled throughout Disney's Saratoga Springs Resort & Spa. They are not located all in one area. If you are interested in a specific area of the resort, you can have this noted when you are booking your villa. Please be aware that if you are booking your villa through Disney Vacation Club, there are now villa categories which delineate which area your villa will be in at Disney's Saratoga Springs Resort & Spa. A preferred villa will be located in The Springs or Congress Park. A standard villa will be located in The Grandstand, The Carousel, or The Paddock.
If you are a Disney Vacation Club member and are looking to book through Disney Vacation Club, I suggest that you call Disney Vacation Club Member Services at 1-800-800-9800. If you are a guest looking to make this reservation using a traditional payment method such as a credit card, I suggest that you call Disney at 407-939-5277 for assistance in making the reservation. Either way, by calling you can explain to the cast member exactly what you are looking for, and they can guide you through the process.
I hope that this information is helpful for you, Catharena. Please do let us know if you have any further questions.
