I figured if the DS is 9 now, by next May he would probably be 10. I don't want to really argue about this, and I am not trying to be snippy at all. I am just intrigued by the magnetism to the dining plan.
Looking at the buffets prices for kids I see they range from 10.99 to 13.99. Well that right there is more than the 10.99 for the day for kids. Add a counter service, and that really is a great bargain! For adults, you have to work really hard and eat a lot to come out ahead.
But I still think that you can eat out a lot at good places, still get your desserts, and have a grand old time away from the kitchen if you eat TS for lunch and eat CS for dinner. You will break even at the worst compared to the cost of the DP. If your son turns 10 before next May, I know you will come out ahead.
