Hi. I booked a plan through WDW site and it is payed for. I have heard that AAA holders may get a discount? Can I call WDW site and see if this is true and if so can I get it taken off my credit card?
If you booked your reservation as Room-Only, then yes, you can call WDW and have them apply the AAA discount to your reservation (if it's available on your dates.)
If you booked a package, then no you can't call them for a discount. You have to go through a AAA Travel Agent to get the discount on packages.
