Hello Sarah!!!!
I would have to say you are one of the COOLEST teens I know!!! I am so proud of you in doing your research and homework to plan an incredible vacation to Walt Disney World!!!
To give you an idea of the promotions Disney World is offering right now to save you money, click
HERE! Once you get to this page, I would click on the Room Only promotion going on right now. From here, you can type in specific dates and see how much a Disney World Vacation will cost. For example, I planned for your family a six night/seven day Disney vacation for September staying at Disney's All-Star Music (most economical resort) with the Quick Service Meal Plan (2 quick service meals and 2 snacks each day you stay at a resort), and your family would pay $2592.68. Now, if your family does not purchase the dining plan, your cost for the same trip will be $1752.92. However, you will then have to budget in your food. I am not sure when your family would come, but understand that the summer months will be more expensive.
A great site to find out what contests are going on right now to win a trip to Disney World is mousesavers.com.
Let me know what else I can do to help!!!!
Have MAGICAL day!
