The 2 y/o won't technically be on the dining plan since they only do packages for 3 & older. You'll either have to pay out of pocket for a child's meal or let them eat off your plate. HTH!
At buffets you can fix them their own plate, and at CRT they are given a plate free of charge. At others you can have them eat from your plate, or order a kids meal out of pocket.
Buffets, family style, fixed price restaurants and dinner shows they eat at no charge. A la carte or CS, you can share with the child or you can purchase a meal specifically for them. If you choose to get the child a meal, then you pay for it, as children under age 3 are not considered to be on the dining plan.
You can either pay OOP for a child's meal, or share from an adults plate, this is for restaurants with a la carte menus. Buffets you can get them their own plate from the buffet, for this reason we did mostly buffets & all you can eats when our son was under 3.
