Of course!

I'm a big time planner, so this board is right up my alley.
As of right now we are booked with a MYW package at AOA for 3 nights with 4 day park hoppers and dining plan. However, I came up with a few calculations and I am really thinking of dropping the dining plan and just paying OOP for food.
Does anyone know how difficult it would be to call reservations and have them take everything off my package except for the room? I don't want to lose our Nemo room in the process of making some changes. My reason for this is that I seem to be able to get everything cheaper if I pay for them seperately. Since I am a florida resident I can get the resident 4 day park hoppers and reserve the room seperately while knocking off the dining plan. Doing this saves me around $840. I'm pretty sure a family of 5 (2 adults, 3 very picky kids) we can eat for less than $840 for 4 days. I am up for suggestions/help!
You guys rock!
