The AP discounts used to be a lot more generous (about 35-40%) but this round for the summer has amounted to $75 off any deluxe resort room, so the more expensive the room, the less of a discount. On our room at the BWI, this translated to only 15%, which was the old Disney Club discount (before it went to 10% on deluxes). A small discount is better than no discount, but with increasing attendance, WDW seems to be pulling back on discounts, or encouraging packages with admission (7 for 5 or 4).
