Every time we go to disneyland paris we eat what we want but cos of all the walking end up staying the same or losing weight. There is quite a lot of choice though most of it is not on the plan. We usually go for the steak and salad otherwise it is pretty much of the fast food variety. Breakfast in the hotel on site is continental. Just enjoy it and you will be so busy walking round and queing that you wont have time to eat! Use the pool and go in the Hurricanes Disco to burn off some cals.
I'm really jealous as I would love to go but cash strapped.lol....
