Hi Lisa,
The
Deluxe Villas are part of the
Disney Vacation Club and members are able to reserve them first for their own vacations. When villas are left unreserved by members, Disney opens them for rent by non-members. If you are having difficulty locating a three-bedroom villa for rent during the time that you are visiting, it is likely that they have already been reserved.
As a Disney Vacation Club member myself, I absolutely love the three bedroom villas. They are so spacious and beautiful. I hope one opens up for you during the dates that you are interested in.
Otherwise, if it turns out that you need to rent three adjacent rooms in a resort, be sure to make a request to have them as close together as possible. This is never guaranteed, although if you have two adults traveling with children, they will definitely do their best to give you connecting rooms.
I hope this helps and that you have a wonderful vacation,
