Yes, I think you can buy through the Doorway to Dreams (at least you were able to during the grand opening) even if you are a member already. It seemed chicago had different incentives than WDW... just as California does...
This must frustrate the guides to have different incentives... but I'm just trying to find out the best deal.
Right now, WDW has $8 off AKV or single Developer points. I was hoping for $8 or AND Developer Points.
