Last time we booked DC, the discount varied depending on the level of your Passport. This is because Passports can be for multiple parks and one or two years. The more $$ your passport, the more the discount for DC.
The variable was so significant in fact that we decided - at the time - to upgrade to Platinum Passports because of our two year plan and the size of the discount for Plat holders.
I'm not suggesting you will be better off going to Plat' ... only saying that's how much it varied.
I believe this is why when you look at the web page of Passport benefits it only says 'DC discount' .... too many variables.
