no need to cancel your reservation. they will just modify them.
from what i have been told,
AAA discounts are pretty much all the time. try seeing if you can use that discount for now. Then when the codes and discounts come out, call back with your same reservation #, and they'll modify it. the difference in the deposit amount will just be applied towards the rest of your reservation.
even if you find another code that will give you an even greater discount after you call to modify it the first time, you can still call back and say "hey, i found this code that i qualify for, can i apply it?" they'll do it for ya.
good luck!!
