That could very well be true, but it is just slight of hand. The discounted rates are still higher then what can be found just a few feet off the property. They just charge so much to begin with that they can slash prices by large percentages and still be more expensive then the competition. How long will it take to get that to sink in to everyones head. Who knows? But it will eventually.
It's like furniture. They can "sacrifice" and slash prices by 50% because they already raised them by 75%. Hey, maybe WDW can have a going out of business sale and miraculously be able to recover and stay open until the next going out of business sale.
