Hi Heather,
Thank you so much for visiting the Disney Parks Moms Panel with your question. It sounds like you are planning a wonderful vacation.
Multi-generational trips to Walt Disney World can be so much fun, and add the celebration for your children's birthdays and it will be out-of-this-world!
If you are looking for a true two-bedroom option, complete with two bedrooms, a separate living room area, a full kitchen, a washer and dryer, and multiple bathrooms, check out the
Deluxe Villa resorts. These sleep at least eight guests. Those offering two-bedroom villas are Disney's Saratoga Springs Resort & Spa, Disney's Old Key West Resort, Bay Lake Tower at Disney's Contemporary Resort, The Villas at Disney's Grand Floridian Resort & Spa, Disney's Animal Kingdom Villas, Disney's BoardWalk Villas, Disney's Beach Club Villas, Boulder Ridge Villas at Disney's Wilderness Lodge and Copper Creek Villas & Cabins at Disney's Wilderness Lodge. You can link to any of these resorts using the link that I provided to the Deluxe Villa resorts, and explore the theme and offerings at each.
There are a couple of other options that you could explore to see if they would work for your family. There are family suites available at Disney's Art of Animation Resort and Disney's All-Star Music Resort. You also might consider a Cabin at Disney's Fort Wilderness Resort. Both of these options sleep up to 6 guests; however, they do not have a dedicated second bedroom. Also the cabins have one bathroom and a kitchen, while the family suites have two bathrooms and a kitchenette. Neither of these include washer and dryer in the room.
I hope that these thoughts are helpful for you, Heather! Please let us know if you have any further questions.
