I think the regular plan is $37.99 per adult per night of your reservation. I forgot the price for children between 3 and 9. My little one could not be included in the dining plan because he is under 3, but we are doing all buffet meals and family style for TS, where he is free to eat there. For CS he can easily share with us (I don't eat large amounts for lunch, plus it will be super hot in July and I will be less hungry than usual).
I am not sure about the deluxe plan pricing. We considered that one but it was just way too much food for us, plus with such little boys like we have, the character meals were the reason for choosing a dining plan, and we are able to do 5 of them for our 5-night stay. Decided to pay OOP for the extra 2 breakfasts, still costing us a lot less than the deluxe plan.
