Heni,
Sounds like quite the group! I am sure fun will be had by all! I think your best bet is going to be a 2 bedroom villa at one of the resorts such as Old Key West or Saratoga Springs Resort. These villas can accommodate up to 9 people. There is a king bed, 2 queen beds, 1 queen-sized sleeper sofa and 1 twin-sized sleeper chair. A kitchenette is in each of these with fridge, stove, microwave, toaster and microwave.
There are also the
Cabins at Fort Wilderness that will accommodate up to 6 people with a fully equipped kitchen. You wouldn't be able to fit everyone in one cabin, but you could always book 2 cabins and request to be near each other.
Last but not least, there are the
family suites at the Art of Animation Resort. These family suites can sleep up to 6 people. There is a queen bed, a full-size murphy style bed and a sleeper sofa in each suite. There is also a small fridge, microwave and coffee maker in the rooms as well. The great thing about these suites is there are two bathrooms and with that many girls in one room, you might need it!
I hope this offered you some suggestions. Keep in mind that if you book two rooms and request that they are adjoining or connecting, it is a request and not guaranteed and based on availability.
