Hi Kathy, and welcome to the Disney Parks Moms Panel!
My family is travelling to the Walt Disney World Resort in September and we chose the
Studios at Disney's Polynesian Villas & Bungalows exactly because they offer two full bathrooms. Their floor plan is very spacious and they may be a perfect choice if the two singles are willing to share a bed.
If you are looking for a more spacious setting, the
Family Suites at Disney's Art of Animation Resort might be even better, because they also offer two bathrooms with an additional bed. They all feature one queen bed, one Double-Size Table Bed and one double-size sleeper sofa. This setting is also awesome because the bedroom door can be closed to provide privacy.
You will also find amazing Villas at the Disney Vacation Club resorts that will suit your party and can be booked by all Guests. All Two Bedrooms Villas feature at least two bedrooms, and once you've decided for one of them, it's just a matter of location. The Villas at Disney's Grand Floridian Resort & Spa, Copper Creek Villas & Cabins at Disney's Wilderness Lodge, Boulder Ridge Villas at Disney's Wilderness Lodge and Bay Lake Tower at Disney's Contemporary Resort will be the closest to Magic Kingdom Park.
To stay close to Epcot, you will find options at Disney's Boardwalk Villas and Disney's Beach Club Villas, while those at Disney's Saratoga Springs Resort & Spa and Disney's Old Key West Resort will give you easy access to Disney Springs.
If you need more help to decide and plan, please, don't hesitate to stop by, Kathy!
May the magic be with you!
Julie
