We were there in Dec. and it was one snack credit for each item. We did what others had mentioned and just had somebody get a popcorn and someone a soda and shared. Ice Cream we didn't share! But, the dining plan was so great and we were so full of food, we ended up on our last day with over 20 snack credits left. So snacks for the road. Most days we didn't even remember we had the snack credits!
