I will be using the QS dining for the 1st time, and am not sure I know all there is to know, despite looking at the various threads on here. One poster commented that it's annoying when people "don't know how many credits they have left and how to use them...." How will I know how many credits I have left? Do I need to track on my own, or does the card itself not keep track? As far as "HOW to use them..." -Is there some other trick to using credits that I'm just not catching onto, or is it pretty straightforward....i.e.--if we (there will be 2 adults and 2 kids in our party) show up for a Counter Service Meal @ lunch or dinner, we each just use a lunch or dinner credit, correct? Also--if we end up doing table service one night....none of our credits can be applied towards that, correct? Thank y'all!
