Yes, all day dining plan is worth if included with adult tickets.
Not sure on the 2 year old but, the dining was well worth it. It cost over $80 just to feed a family of 4.
The dining plan is definitely worth it and you're able to share with children but you do save money with the dining deal.
I don't know about the 2 year olds, but we did the dining plan and it worked great. I was apprehensive about it, but I'm so glad we did. You get a wrist band, there is a list of approved eateries, you can eat once an hour and it was good food.
They can eat off your plate. It is worth it if you eat at least two meals.
