I'd like to share a couple observations.
First of all, when I first heard about this I started playing with the numbers. Since yesterday afternoon, the Disney website is showing a number of room classes as "unavailable" that were widely available last night. Looks like they have removed some rooms so they won't be available for this offer.
Secondly, I'm not mathmatician but I am cheap, and I've been playing with the numbers since yesterday.
Yes, it is potentially a good deal. However, not much better than AP discounts we've received in the past. I personally do not like to be locked into a package. Especially with the economy today. I like the room only booking with the 5 day cancellation. I'm nervous about switching to a package to save a couple hundred dollars. The savings for us isn't won't be much if we are required to buy tickets when we already have AP's. Plus if we have to pay in full 45 days ahead with no option for cancellation, ouch.
My question is how many people will book? Will they fill enough rooms that there will be no discounts later? I never count on that AP discount of course, but we've been able to secure one in the last two years and they are nice! If they fill the rooms with this promotion, chances are slim they'll be discounts left for the rest of us.
In any case, I hope everyone takes the time to really look over the financials. Disney's goal is to make money. They can offer room discounts and make up the difference on all the other places we spend money at Disney. How much more will you spend on a 7 day trip than a 4 day trip? Even if the room is "free"?
