Hi, Joanne!
Your question is really fun because my very first trip to Walt Disney World years ago was during the week of Easter and there were 6 adults plus 2 kids on our trip! I'm so happy that you're already working on planning your magical vacation this far in advance. I think it's so important to have all your ducks in a row as early as possible.
We have booked vacations through AAA before and I really like the little extras they give, like their AAA Diamond Parking Pass that will provide you with an up-front parking spot close to the entrances of the Theme Parks. Their special Story Time is really fun too! What I would do if I were you is get a price quote from AAA as well as the Walt Disney Travel Company and see which one offers you the best rate.
With your party of 10, you could organize your room a couple of different ways. The 2-bedroom Disney Vacation Club Villas sleep up to 8 people. There are also the
Treehouse Villas at Disney's Saratoga Springs Resort & Spa, but those sleep up to 9. When we stayed in one of the Treehouses, if we had an infant with us, they would allow the baby to sleep in a pack-n-play, so, depending on the ages of the 4 children in your group, that might be an option. I think the very best option for you would be 2 Family Suites at
Disney's Art of Animation Resort. Each suite sleeps 6 people and has 2 full bathrooms. I think this would ensure that everyone is comfortable during your vacation.
I hope this helps! I'm running out of room for this answer, but please feel free to
send me a follow-up question if I can help with anything else!
Have a Pixie Dusted day!
