Upgrade cost from basic to deluxe dining plan?

[frannn]

I know there used to be a sticky with this info on the dining board, but I can't find it. I need to call today to upgrade and want to make sure they don't overcharge. We're aready paying for the upgrade from the free QS to basic dining, so I'm not including that in my calculations. I just want to be sure they are not using the crazy higher numbers per night I was just given by a random CM (which differ from what is on the 2011 dining sticky). We are 2 adults, 1 child. I'm thinking it should be 760 upgrade cost for the 10 nights we are there. Is this correct, or am I missing tax or something?
