Call your travel agent.
I would check the Disneyworld website for any promotions they are running for the dates you plan on going. Prices vary depending if you are just buying park tickets or if you are buying a package including resort stay.
I did a vacation room and dinning plan for 3700 for a week
It depends on the number of days and ages of children. You csn get pricing information on the disney web site, but expect to pay roughly $100 per person per day.
