I agree with the last poster's advice--if you take a look at the menus, you can tailor your trip budget around the restaurants you select. Then--stick with it (the tough part). That said, we did the half board and found that it was really quite a money saver as all anyone needed in the afternoon was a snack. Are you staying on property? Your hotel may offer a continental breakfast that will assist with budget planning as well, as the Hotel New York did for our stay. I would bring your own snacks too, as we found those unconcious hot chocolate purchases (it was November, btw) and snacks on the fly were a drain as they are at any Disney park. Finally, suggest to your children over the course of the four days, that they can make a list of souvenirs they might like, and on the last day, review the list and see what they truly can't live without. That helps with the impulse buys as well. Have fun!
