Keeping meal tokens separate with Dining Plan?

[JJsmama]

I'm taking my 2 sons to WDW with my mother and my sister and her two sons. We're all on the same reservation (2 rooms) and have the meal plan. Will there be a way to know how many each 'family' has used so it will be equally shared?

I'm not completely sure, but I know that when looking at the bill there is an indication of which room key was used for charging at stores and restaurants. I'm don't know if this will work with Dining Plan.
