PLUS - you can exchange one quick service for 3 snack credits as long as you use all three at one kiosk.
DH and I looked over the food before we left and we used a few QS credits and we would each get a food item and then a drink to share - it worked out really well for us.
(We did end up with all of our snack credits not being used but we grabbed trail mix to bring home with us)
