My suggestion would be to go ahead and plan your ADRs now. With three little kids, the last thing you want to be doing is walking around looking for someplace to eat. When you get up in the morning, if it looks like that reservation is not going to work for you, call from your room and cancel, and make one where you are going to be.

If you are in a park without a reservation, walk up to Guest Services near the front of the park. They have access to all the restaurants in the park, and can see what is open and at what time. That will be much quicker than walking around the park.
