Hi Daina,
Welcome back to the Disney Parks Moms Panel! I am pleased to assist you today.
How exciting that your sister-in-law can now join you for this amazing trip. If one of the children is 2-years old or younger, I would suggest that you try booking one of the Treehouse Villas at
Disney's Saratoga Springs Resort & Spa to keep the family together. We have stayed at Disney's Saratoga Springs Resort & Spa in a 2 bedroom, villa. It was lovely. There were six of us, four adults and two kids.
If all of the children are 3-years old and over, I recommend that you try a 3 bedroom grand villa at
Disney's Copper Creek Villas & Cabins at Disney's Wilderness Lodge. The 3 bedroom grand villa sleeps up to 12 adults. The villa includes one king bed, four queen beds and one queen-sized sleeper sofa.
A more affordable option might be two family suites at
Disney's Art of Animation Resort. The family suites sleep up to six adults. And, best of all, the family suites include a kitchenette and two bathrooms. The kids will love the Big Blue pool at this resort!
Daina, since your group has expanded, be sure to make
dining reservations! It will be hard to walk-in to any table-service restaurant and get seated with a group of 10 people. Hopefully, you have created a My Disney Experience Account. Once you have done so, be sure to add everyone to "My Family & Friends List." Then, you can make dining reservations and Fast Pass+ selections for everyone!
Magic, memories and Minnie Mouse hugs,
Donyell
