It really depends on how you and your family eat. When we are at Disney, food is not our focus. I just can't spend 1.5 to 2 hours in a restaurant when we could be running around the park having fun! Counter service meals are fine with us! We can eat when we are hungry and we don't have to manage our time around a reservation. I have younger children so I don't have to worry if they are going to have a meltdown in a crowded restaurant while trying to waiting to be served.
If we have an ADR, we make it for a day that we are not going into the parks (ie. 1900 Park Fare, AKA The Grand Floridian). That way, we can relax and have a nice meal without having to feel hurried.
Just remember that there are plenty of places to eat decent food in WDW that do not require ADR's! You are not going to starve if you don't have them. I felt like that after reading these boards before our first trip. I was so nervous about not getting them. When we got there and I started to look around, I realized that there were TONS of places to get food!
There are a lot of ways to plan your Disney trip! This board is a great resource. You will find people that have to plan every single meal and others who are the grab and go type (we are the latter!)
You will find your own Disney vibe!
