through Disney in order to do the Disney dining plan? I was considering doing the dining plan but already but one 6-day hopper. Is it possible to still do the dining plan? I haven't bought my dd's ticket yet.
No, the DDP must be purchased as part of a pkg which includes room at rack rate and at least a one day MYW ticket. I have an AP, have done the DDP three times (will be four when I go next week) and each time I've had to purchase a one day MYW ticket. Of course, you can always save the one day ticket to use at a later date.
I know I said you had to pay room rate for your room (and normally you do), but you can use an AAA rate and for my May trip Disney had a code that allowed for the DDP to be purchased and still gave a slight room discount (not as good as the AP discount though).
Is there an admission purchase requirement?
With the exception of guests staying at DVC resorts on DVC points, you must at least purchase a basic one day admission ticket, but you do not have to purchase a ticket that matches the number of nights you are staying.
