Tink, you should relax before you post such fanatical loyalty to the DC card.
I don't know why the heck you quote March rates, when I base my words on my experience booking for August. The CM at CRO quoted me a rate for DC and another for AAA. You know well that there are no codes published as of this date for the end of August. I ended up picking AAA's, namely WEG code (WGE, WGD, WDG or something like that - I was not paying attention to the code) Because it saved me more money than DC. As far as I was concerned, I did not need DC for a thing.
Don't be so fanatical about it, guys. I have yet to see a time when DC room rates beat codes and other discounts. For all that loyalty, Disney does not give anyone a free night anywhere, so just keep the options opened for anyone considering membership in the club. Unless you shop at the DS often, you won't get your membership's worth any time soon.
