How long do I have to upgrade my dinning plan?

[leitadisneyfan]

So, I was able to get free quick service dinning plan for the fall. Right now it is cheaper for me to pay out of pocket for the table service but if I add another table service then the up grade would be cheaper. How long do I have to upgrade a month before, a week before the day before my trip?

Any changes to your package must be made within 72 hours (IIRC) of check-in. Inside the last week or two, there may be a change fee associated with that as well.
