Is it worth getting the dinning plan for a 2 day stay(pros and cons)

First time we used the DP it felt like a lot of food for us. Last time we stayed off site so it wasn't an option. This time we are taking a quick trip and will only do 4 days/3 parks. I'm leaning towards the Quick Service DP. You get 2 quick service meals and 1 snack per day. It works out to about $40 per person per day and this time I will have 2 teenagers park hopping in another park for 1-1/2 days. Normally that's a lot, but Disney is expensive & last time we were there I believe the Mickey bar alone was about $5.
