Does DL-DCA have a 2 day hopper pass or give DC Discounts?

[Disneyfun1]

We may make a trip to DL and DCA this next friday and sat. I have already 4 adult 1 day admission tix to either park that i have received for gifts through the year which will take care of mine and my wifes passes. I need to buy my childrens passes though. An 11 year old(adult) and a 9 year old(child) for each park. Do they have a 2 day hopper pass cheaper than buying all 1 day passes? or do they even have that? Am i stuck buying 1 day passes for each? Since ours are not hoppers, we wont be able to hop, unless.....can we upgrade our 4-1 day passes to hoppers for the 2 of us? Also, on 1 day admission, do they give AAA or DC discounts? thanks.
