Hi, Ashley! There are many variables that will determine how much a WDW vacation will cost. For a ballpark figure, click
HERE for the Vacation Booking Guide. Select your party size, type of accommodations, and although you can't get a price for 2012, select dates for 2010 (try to pick a week/month close to when you plan to go. For example, September will be cheaper than traveling in July, so pick a time that will resemble your desired vacation for best results.)
This Guide will allow you to add in everything from tickets to dining, so you can get a great idea of what your vacation will cost so you can start saving up! Remember, you are talking several years from now, so costs are bound to be higher at that time.
Have fun as you begin the planning process and we'll see you in WDW in 2012!
