Hi T.!! I am actually planning a trip for four of us for Christmas time. I have actually found that the cheapest way to plan this trip is to go the the DisneyWorld website. They have hotels called "All Star" hotels. THese are the cheaper ones, $79 a night for off season and you still get all of the benefits. They pick you up from the airport for free, and you get free bus rides every day to wherever you want to go. They also have these Magic your way tickets with Dining. This is really the way to go. For each night that you stay at the hotel, each memeber of the family gets 2 meals and 1 snack anywhere in the entire Disney area including resturants and stands at all parks.
Good luck and let me know if you have any other questions!
