Hi Susan,
Congratulations to the Class of 2013! I wish them much success!
I would recommend staying in a family suite at either the
Art of Animation or
All-Star Music. The beauty of the suite is it will sleep up to six, you have a kitchenette AND two bathrooms! With teenage girls, the extra bathroom will make things easier for everyone to get out the door.
Also, think about arriving on a Tuesday or Wednesday when flights are cheaper if you plan to fly. Sign up at your favorite airlines website for deals which are released on Mondays, Tuesdays and Wednesdays.
You also can order breakfast foods, snacks and waters from the Garden Grocer. This online grocer is wonderful to order all the supplies you need to your resort. They will have bell services store the order until you arrive. They will even store the perishables. Just with savings on the items I mentioned, you can save a lot of money.
Disney does have great deals on rooms right now so head on over to the site and check them out.
Congratulations and wishing you a wonderful vacation!
Beth
