We were left with so many QS credits simply because we couldn't eat 4 QS meals at lunchtime, therefore not using 1 or 2 daily (which mounts up over an 18 day stay!!). We also were out of Disney for 4/5 days, therefore not using a further 4 QS at lunchtime (x 4/5 days). Now can you see how we had a ton left With having a TS meal for dinner every night, we couldn't use any spare QS then. We typically don't really eat breakfasts so couldn't use a QS then either! We tried to convert our QS into snacks in the resort but cashiers said it couldn't be done, I tried though.
