Just to add a few words to what I already said a couple posts back, I work at Walmart and have been there 11 years. At Walmart, as well as all other retail businesses, we put things on sale or on clearance. Generally, the difference between the two is that if it's on sale (rollback, in Walmart terms), it's an active item that we will continue to carry, but they're trying to move that product. Eventually, the price goes back up, but in the meantime, they're trying to entice more people to buy the item, or at least to get in the store to look at it, and then end up buying other things. If it's on clearance, it's a deleted item, such as something seasonal, and they want to get it out of the store and make way for the next season of merchandise. This is why you see so much stuff on clearance after Christmas, for example. But back on topic, my point is, that when we have a product that isn't selling as much as we'd like, in order to move that product, we mark the price down. That's a common business tactic when you have a product that isn't selling as much as you'd like.
Being the marketing geniuses that the Disney execs are known for being, I would think that they, of all people, would be the first to realize that if they want to move their product (in this case, rooms at their resorts, and the accompanying tickets), the answer isn't to start reducing the quality of the product, but by putting it on "rollback", if I may borrow Walmart terminology. Knock 30 or 40 bucks or more a night off the price and more people will be booking rooms. Simple as that.
Again, I may be making a mistake to actually assume that these people are intelligent. But they didn't get where they are by making idiotic decisions, so I'm guessing that they know the basic principles of economics and how to move their product. So again, I'm gonna assume that there are other reasons than economics as to why they are making this move.
