And our point is you're wrong. It's been like that for years and for whatever reason the system works fine for Disney, Orbitz/Cheaptickets/other online sellers, and customers. I've booked multiple Disney hotels at the 15%-30% and then used an Orbitz coupon for an extra 15%-20% off. The catch is you have to pay for the whole hotel stay upfront. And sometimes now there is a cancellation fee with Orbitz. Welcome to stacking discounts for Disney hotels!! (I couldn't believe it when I discovered it a couple years ago either.)
Disneyland and WDW are definitely different...no doubt.
But what you're describing is very rare at WDW...so I may be just comparing apples to oranges.
I think it's just as likely that the 18% is the price they had set all along after buying the rooms from Disney...and it's just rolled out as a promo.
Then the "extra" is a legitimate discount off whatever their predetermined target price was.
I do have experience In wholesale...albeit at WDW which is different. For instance almost no one books WDW through Expedia...it's just not how it is. I also see Disneylanders booking standards assuming upgrades...that is not the case in florida because they don't do upgrades for the sake of upgrades - it's to balance inventory and compensation and that is rarely used. Just two different things.
If you have technical insight into Disneyland offering additional discounts to wholesale sites...then I yield. It could be that way. But not guaranteed because it seems it works that way. It's kinda illogical.
Disney wants the rooms filled...but once they sell to orbitz, they have their money and are out of it. More discounts drives sales away from travel company where they DON'T have the money yet.
Wholesale will extends some blocks...like if I'm an agent and call and say "I need more rooms for 10/1 and I'm almost out"...Disney will throw me more if available.
But they typically wouldn't call and say "hey...we're rolling out a 20% next week...so why don't we give you an extra 20% off too, buddy?"
Why do that? It makes no sense.
