Yes. There are some three-bedroom villa-style rooms that sleep up to 12 people. These rooms have three full bedrooms as well as a living area, kitchen, and multiple bathrooms. For information and pricing on these rooms, you should call Disney reservations at 407-W-DISNEY. However, I should warn you that there are relatively few of the three-bedroom villas, and priority for them goes to Disney Vacation Club, so you may possibly have trouble obtaining one of them. Depending on the ages of the members of your party, you may also be interested in a
Treehouse Villa, which sleeps up to nine people, plus a child under the age of three in a crib.
As an alternative, you could more easily get a two-bedroom villa (which sleeps 8) plus a one-bedroom or studio villa (which sleep four or five). Other possibilities include two connecting rooms at a deluxe resort (these rooms sleep five each), two All Star Family Suites (which sleep six each) or a row of regular rooms next to each other.
Again, I suggest you call Disney reservations to discuss the pricing and availability of each of the options to figure out which is best for your needs.
