I know that when we went to WDW in March of 2001, we got a very good discount at PO-R. It was under $100 inc tax. We haven't been since, but I booked a room at ASMo for February using the BRH code and I wasn't impressed with the rate - $84 before tax. I inquired about an AP rate, but there are none right now and don't know if there will be any for that time period. I thought of buying an AP just to get a better discount if the math worked out.
It seems very easy right now to book a room for next month and to get PS's. So I think attendance must be down at WDW. I don't know if they're charging more because less people are coming, or if more people would come if they charged less. I'm sure Disney spends millions of dollars on research about this type of thing.
