In order to understand the revenue situation, you need to look at more than just the number of rooms not booked by those who don't like the program. Disney's not stupid and I'm sure they ran surveys to see if passholders would be accepting of the program.
The small number of AP holders who will not book with BR is not a large amount of money lost. The Best Rate program was implemented to increase revenue in two ways:
1) To reduce payroll at CRO. The bulk of CRO's payroll hours & overtime came when AP rates or other major promos were released. Having been a CM for quite awhile, I have no problem saying that Disney has a major issue with excess payroll, particularly overtime. Because of this, I imagine we'll probably be seeing more "special" rates that will only be bookable online.
2) By requiring a 1 night non-refundable deposit, they put an end to the many people who booked rooms at the AP rate, only to cancel them days before the deadline. Again, every one of these cancelled rooms are esentially lost revenue. They could have gone to another passholder or even to someone booking at rack rate during particularly busy seasons.
When you combine the payroll expenses with the revenue lost from the rooms, it greatly outweighs the money lost from the small number of people who won't book because they don't like the new system. Just as there are people who don't like BR & won't book online, I'm sure there are those who will now book BR because it is available online. (I became one of those people).
When I first became an AP holder, I too got all caught up in the waiting & hysteria that is so prevalent on these boards. I finally got sick of it because it just wasn't worth it. I wasn't an overly picky person who had to stay at a particular resort or particular room type, so I just said forget it & bought DVC.
Now that best rates are available online, I'll definately be booking our non-point nights through the BR site, as I'm sure many others will.
