AP holders do not get a discount on the price of the
DDP. The only thing is that if you have an AP you do not have to purchase a one day MYW ticket as we have in the past. Adding the DDP does change it into a pkg though, meaning it must be paid in full by 45 days out and is subject to the same cancellation and change fees as any other pkg. The price is:
QSDP- $29.99 for adults and $8.99 for kids
Basic DDP- $39.99 for adults and $10.99 for kids
DxDDP- $71.99 for adults and $20.99 for kids
If you happen to be going during times certain discounts are offered, (i.e.
free dining or for the buy 4, get 3 days free), you can not use your AP for room discounts and still get the other discounts too. Instead you must pay rack rate for the rooms and buy at least a one day MYW ticket for everyone in the room. You can then save those one day tickets to upgrade your AP the next year. I know you didn't ask this, but the question gets asked alot on here.
