Meals not covered under the plan are the meals you are supposed to pay for out of pocket as they are the cheapest of your meals. The general rule is to always use the plan for your most expensive meals.
In your example of staying 12 days (11 nights), I am assuming you are testing the Regular Dining Plan. You would have 11 QS credits and 11 TS credits. Once you go over the number of credits, we then order the restaurants by "cost per credit" and put the cheapest ones past number 11 on the "Meals Not Covered Under Plan". That simply means the 11 meals under "Meals Covered Under Plan" are the meals you should put on the dining plan and meals 12 through number X are the ones to pay for out of pocket. Please let me know if I did not explain it well enough.
The term "Additional Cost" means the meal plan is not cost beneficial for your particular trip and meal selections. If the numbers were in your favor, you would have seen something like "Savings: $125.40". The "Additional Cost" amount is the amount the specific meal plan costs above the total of the meals under "Meals Covered Under Plan". For example, if the 22 meals/credit (QS + TS for your 11 night trip assuming all 1 credit TS meals) cost a total of $1722.65 and you had an "Additional Cost" of $125.40, that means the dining plan cost $1722.65 + $125.40 and you would be over-spending by $125.40. Again, please let me know if that does not make sense.
If for some reason you think the credits are being mis-applied, please copy the dropdown for the details and send us feedback on the site to make sure we do not have a restaurant mis-labeled as 2 credits.
I hope that helped. Always feel free to send us direct feedback on the Feedback link at the bottom of the page.
